well if you are having trouble changing the update block list servers, i would just shutdown peerguardian untill this has been all sorted out. (make sure to disable peerguardian updates aswell as disable startup with windows.)

reason: there are different versions of the software that can be configured differently and i dont really have enough time right now to give instructions on how to change them. maybe LOTR or someone might come along and help.

the instructions posted are for the latest version of the PG software.
