Rare, AW... Very rare for Adaware to ever do anything to a BS file, right ?
I mean, I have NEVER seen that... Ever !

Wondering, davexxx, have you possibly enabled AdWatch ?
Doing so can be extremely problematic with any progs that need, in anyway, to alter registry values.
(Easy to get into some incredibly frustrating loops that will end with you uninstalling Adaware and then immediately bunging it right back in without AdWatch enabled !)

Also, you haven't exactly overwhelmed us here with any details, eh ?

I mean, WHAT BearShare version and what ELSE may have occurred and/or changed since your last successful BS session ?
What updates to whatever... ?
