as in:
despite the fact i kill EVERY OTHER NON ESSENTIAL PROCESS that isn't avira, it doesn't let me stay on a server.
i don't know why it worked on a clean boot.
so you are disconnected then?
if it's working on a clean boot, then your account is for sure in the clear
which means it must be some program that you have running
if uninstalling programs until it works doesn't work, then you may only be able to play on a clean boot or on other computers (or reinstall everything, I don't envy that)
