Ok, so, yes, I have already tried running in compatibality mode. Disk can't be dirty, because when I tried reinstalling it and it auto played, it worked fine. All plugins were there ( NAM and Real Highway needed to be reinstalled ) and it was fine. Exited out to install it and some more plugins. Click on icon and the little blue circle spins near my cursor for about 2 seconds, then quits and does nothing. Yes, it is disk 2, not disk one. Will try task manager.

Tried it, but the disk isn't even spinning in the drive, let alone task manager showing anything. For some reason, though, it lets me access the files on the disk. ???
