Probs With RecordNow

Running xpsp2 on a viao pcv-rs720g. Only add on is a graphics card. A friend of mind told me a way around having to put a game cd into the drive every time I want to play. Simple, copy the game to an iso, create a virtual drive, change a game file to search the virtual drive instead of the d: or e:, ect.
Problem is when I try to copy the game to an iso, about halfway through, I get the message
Sense: 00 ASC: 00 ASCQ: 00 (Command 00)
saying these files are missing. I looked in the system32 folder (where I would think they would be) and they are all there. Tried just going to add/remove programs, selected recordnow, and it gave me an option to fix. Still, same problem. Any ideas?
