damn, QIP 2010 is messing with me /: it's stupid
it doesn't want to connect to ICQ. It connects to its own QIP network, but it absolutely won't connect to ICQ, while 2005 connects to me normally. And no matter how many times I restart it, it won't connect for a certain amount of time (up to several hours!).
I'm going to delete it and install Infium /:
