Quickbooks restore issues with disk and errors NEED HELP URGENT

Hi, hopefully someone can guide me.  We had a problem on our computer (Running XP) did the service pak 2 update not knowing we were majorly infected with spyware, this caused windows to go bonkers.  After many hours on the phone with Microsoft it was determined I had to reformat my system from scratch to rid myself of spyware.  We spent 8 hours on the phone trying to resolve the issues, kid you not.  Anyways, I did manage to get into my Quickbooks Pro 2003 program and do a back up, I have 4 sets of books I backed up.  The backups went fine with no error reports.  Well then it gets better, I could not find my 2003 program and had to install the Quickbooks Pro 2004 in its place, went to restore, and it would get to 80% then stop with an error of "unable to read this device"  So after reading I did take that disk to a Data Recovery place, they did manage to get the disk to be readable and goes through the back up but does not tell me it backed up successfully.  So I was able to retrieve 2 sets of small books but not the two main ones, Disk 1 has all of one small company on it, and the beginning of a big one.  I have not been able to get them to fully restore.  Below is the three different errors I have encountered, if anyone can guide me or help me, it is so frustrating to see the files there but not get them to fully restore.  To re enter all this work is ungodly and my taxes will be due soon so Im in overdrive to get this to work.  Please this is URGENT, Im so close but just not able to get it 100 percent back, or if there is a way to open up the quickbooks and drag and drop the files to build my books back would be an option if at all possible.  I am able to pull up the files, they are there, HELP.

First error was:     The instruction at 0x004075FF referenced memory at 0x02ec386c The memory could not be read.
Second error was:   C=88 Quickbooks error C=value
Third error was:  Windows\temp\crash.xml   and Windows\temp\crash.dmp


Thank you so much,
