[AG-TECH] AG Toolkit 2.4 fails to start

I installed an AG Toolkit v2.4 on an XP SP1 machine according to specs and when I try to start the venue client, it will abort. In debug mode it says  "Initialization Error:  unpack list of wrong size" right after it started the Certificate Request Wizard. Anybody knows what the heck this is? I am lost and would need a solution real quick!

        Heheh.. yea.. quite right. Ooops. I hate that word for how often I
misspell it. I really had to make sure I got it right in the source code
for AGVCR. For emails, obviously I'm still having problems. :)
