I don't think Microsoft is supporting let alone doing updates to that old OS.
Surprisingly enough, they are, and more frequently than you might imagine. I have turned of the automatic part, but I always know when they send one.
Even if that's not the case, a system restore can back you out of some other trickery.
System restore won't hurt anything, and there's a good chance it will correct the problem.
ateno...Do you have the same problem if you insert VSC from the toolbar, instead of adding it to the FX bin of an audio track?
Do you have problems with any other DXi's?
