Can't receive any ICQ messages

[David Hasselhoff]

Hello!
I have a problem with Pidgin and ICQ. I can send messages just fine, but 
I can't receive any messages from my buddies. Debug window states 
"message received" but nothing is shown in my message window! I'm using 
newest Pidgin version on Windows7 32Bit. (Jabber is working fine though 
and I already tried the "use global proxy" option - didn't work)

I hope you can help me!

Thank you.
