Patches aren't playing correctly

[danbeaulieu]

Hey guys,

System:
Cubase 4.0.3
Virus TI 2.0.5
- Driver: 2.8.4

Short version:
Basically upon saving and reloading, one of my patches in my song is playing all fucked up and nothing I do fixes it. I never messed with any parameters after creating it.

Details:
Yesterday it played awesome... I mixed down a copy of the song into a 16 bit 44.1kHz wav file to burn to a cd. Sounded great on the CD but the vocals needed to be touched up. A few hours later I booted my system back up and one of my patches is all screwed up. Its fading in and out and the cutoff is turned about 30% up. Also, It sometimes sounds like its going through a reverb channel though its not.

Things I've Tried:
Reverting to an older version of the song.
Extracting Midi Data (Cleared Automation).
Recreating the patch.
Deleting the midi track and re writing it.
Putting the patch on a different channel.
Complete System Restore.


Somebody please help me before I rip my face off.

Thanks,
Dan


p.s. If it comes down to it, I have a version of the sound playing correctly and a version playing messed up that I can upload... If I must.
