Holy crap! Huge thanks for the heads up guys, hope you can get your Viruses to work again. Please keep us posted. Be sure to completely delete all the Virus TI software from your PC too when rolling back.
The full folder: C:\Program Files\Access Music
The full folder: C:\Documents and Settings\All Users\Application Data\Access Music
There might also be some registry entries that may need deletion.
When you roll back, does your Virus LCD confirm you are on the correct version?
Here's what I could find about resetting the Virus TI:
