Trillian won't connect on 3G

[Meister_Li]

Oddly enough, other Messengers and Web-Applications work fine on 3G, only Trillian does not. It works fine on Wifi, tho. When trying to connect on 3G, it endlessly circles between "Signing in" and "Reconnecting" and never gets to the contact list. This worked fine a few days ago. I cleared all application data and uninstalled and reinstalled it already, with no success. I use a Galaxy S I9000 with Android 2.2.1

Thanks for the help.
