My Registry cleaning program freezes at startup

My system: Dell inspiron 1501 laptop, OS is Windows XP Home Edition.
I bought a registry cleaning program XPMedic some time ago. It worked for a while, but now it freezes every time I start it up. When I try to get it off my screen (pressing Ctrl+Alt+Del) I am told it is not responding. And when I close it I am asked whether I want to report this to Microsoft. Numerous efforts to contact technical support at support@xpmedic.com have nearly driven me mad. It took 15 emails and five weeks to get a response. They gave me link to re-download the program and a new license code generator download. I took off the old version and disconnected from the Internet and switched my Firewall off. But the same problem recurred. It froze immediately at start up. The technical support from Xpmedic, told me in the one email they replied to that if it didn't work they would refund the money if I sent the license code etc. I will probably end up doing this, but I am curious to know what might be wrong and would like to fix it if I can.

It may be a conflict with some of the Dell software or services. If you boot into Safe Mode, does XPMedic work without freezing?

time to use another reg cleaning software. I'd suggest you try "system mechanic". I've used it personally and it has lots of features such as removing duplicate files and folders.

Yes when I run from Safe Mode the program works perfectly? How can I identify the program which is causing the problem?

We're nearly there. I followed your suggestions and eventually discovered the clash is with the DHCP CLIENT (in Services). When I un-tick this it works. Is there anyway of resolving the clash besides unticking this service (I think my connection to internet wont work when it is unticked). Obviously when I want to run XPMedic I can simply untick DHCP and restart. Then reverse the procedure to get my internet connection.
Are you running XP SP2? I ask because I've been able to use XPMedic on a PC running DHCP without issue. Are you current on all your Microsoft updates and patches?
i agree with souseran. check to see whether ur pc is up to date on all the ms patches.
My OS is Windows Home Edition SP2. My automatic update is on and I have also updated from the Microsoft Update site manually. But. This does not solve the problem. With DHCP enabled it wont work. With DHCP disabled it works perfectly.

I unchecked the LMHOSTS box in WINS and the 'Disable NetBIOS over TCP/IP  was unchecked in any case. However this made no difference. The program will run perfectly when I uncheck the DHCP in Services. When I enable DHCP it does not work. Disabling DHCP is not an option because my internet connection goes wallop when I do it.
What I am doing, from time to time, is disabling DHCP, restarting, running XPMEDIC, then enabling DHCP and restarting. Not perfect, but it works.
Just a shot in the dark, it shouldn't cause any havoc in the system though.

what if we re-registered all the components related to DHCP?
go to a command prompt and run the following:
regsvr32 Dhcpcsvc.dll
regsvr32 dhcpssvc.dll
regsvr32 mdhcp.dll
regsvr32 dhcpmon.dll
regsvr32 dhcpsapi.dll
did u ask them how xpmedic could be interfering with the DHCP service?
Re Reregistering all the components connected with DHCP service.
I'm not sure if I did it right, but here are the results:
egsvr32 Dhcpcsvc.dll -     Result: D... was loaded, but the Dll register server entry point was not found
                                                          (the file cannot be registered)
regsvr32 dhcpssvc.dll-    Result. Loadlibrary ('dhcpssvc.dll') failed - The specific module could not be found.
regsvr32 mdhcp.dll-         Result: Dll Register server in mdhcp.dll succeeded.
regsvr32 dhcpmon.dll      Result: Same result a first above
regsvr32 dhcpsapi.dll     Result: Same result as first above.

By the way I will notify XPMedic support to see if they have any response. However getting an answer from them is worse than getting blood from a turnip. But I'll try.
I got no response from XPMedic Support. Am not surprised with this. Their technical support is abysmal
