Digital rights failure on downloaded movie

I recently bought a Samsung Galaxy tab, and part of the deal was to be able to download some movies from Samsung's movies site. I have downloaded several movies, but they won't play. Samsung help has been unable to resolve this. Can anyone there help?

I'm using XP SP3. Here's the problem I get:

If I click on a movie, Windows Media Player opens but I get the message "You do not have the rights to play this file. Go to the contents provider's web site to find out how to obtain the necessary rights: http://msdrmacetrax.com/GetPullLicense.asp" If I go there, I get the message from msdrm.acetrax.com "An error has occurred whilst storing the license on your computer (Error Number: - 2146823279. Please contact support"

Samsung apps help told me

"1.Solution 1

go to http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp with Internet Explorer and run the update. Retest to play the movie afterwards

2.Solution 2

- Backup the files of the directory C:\ProgramData\Microsoft\Windows\DRM\

Windows Vista/7: C:\ProgramData\Microsoft\Windows\DRM
Microsoft Windows 2000 and Windows XP: C:\Documents and Settings\All Users\DRM
Windows 98: C:\Windows\All Users\DRM
Windows Millennium Edition: C:\Windows\DRM
 
- delete ALL the files in the folder: C:\ProgramData\Microsoft\Windows\DRM\ as well as the files in the “Cache” folder beneath

- Retest to play the movie afterwards. If it doesn't work, restore the files which have been backuped before."

This didn't work. I told them

"Solution 1 gave the same problem after the update even if I rebooted after the update as the site suggested. When trying to play the file afterwards I also got an error message something like “You have reached the limit of licenses for this movie”.

Solution 2 is not possible – I am using XP and there is no folder C:\Documents and Settings\All Users\DRM on my computer."

Thanks.
