I have the same problem attempting server to server transfer. I don't even have that probelmatic hotfix on my machine.

I tried disabling XP firewall and AVG and iI get this in the status window:

I then tried a different receiver server and everything just hangs in the queue.

What can be wrong?

Thanks
