Others have commented that they are having similar problems. You log-in and the clips will not play. Well, here is the solution, I did this and am now able to view RW clips with no problem on any computer.
1 - You need to delete the DRM folder on your computer. It is a hidden system file so the first thing you need to do is change your settings to view hidden or system files. Open windows explorer (Start-Run->explorer). Then select the 'Tools -->Folder Options' and then select the 'View' tab. Select 'Show Hidden Files and folders' and Uncheck 'Hide Protected operating system files:
2 - Once that is done, you need to delete the DRM folder. For Windows XP it is located here:
C:\Documents and Settings\All Users\DRM
3 - Once you delete that folder go here:
http://drmlicense.one.microsoft.com/Ind ... ndivit.asp
This will start the DRM from a clean state, which resolves most DRM issues.
Enjoy!
