Brother I feel you pain! *Just flip back 1 or 2 screens for the problem I'm still having with my M-Audio 2496 PCI card and Win7. It seems as if Win7, Reaper, and the M-A drivers don't want to play nice. *No resolution yet, and I'm 2 steps away from chucking M-A and going to an Echo. *I'll try registering and going*to M-As support first. *So far I've spent more time chasing this problem than making music. *Glad this worked for you.*
