Hmmm, it sure does sound something else was messed up good before you installed this hack. I'll still install vbadvanced regular on 3.0.1. here to see what it does, but I can't guarantee anything.
If there's something specific to vbA and 3.0.1. in accordance with this hack I'll find it, if not then it appears your board's prior state is likely the culprit somehow.
Sadly you have a looooooottt of hacks installed, as you say, or I would suggest upgrading to vB 3.0.3. and reapply vbA and this hack. With a board that start working like magic, who knows what can happen?
Speaking of which, we know it works on CPMS, since this we tested. The 'diet' version as yet goes untested, so this I'll take along with it on my todo list.
