Did all that. Reset to factory doesn't fix this.

The error message saying the directory does not exist is wrong... the directory DOES exist, and the real drum is in it

The same song in BIAB finds and plays the real drum... so the directory settings in BIAB are correct. Its only in RB that I can't generate realdrums.

I'm wondering if that last blue screen crash changed something on the hard drive that RB needs. As I write this I'm reloading everything from the USB hard drive to see if it overwrites any hard disk errors that may have been caused by the last crash.

Will report back.
