AvantGo KPilot 4.5.0 (baby)

Hi all,
I upgraded my system to SUSE 9.3 with KDE 3.4.0 Level "b" and KPilot 4.5.0 
(baby). Synchronisation with the AvantGo-Server does not work for me anymore. 
There's always the following error in the log:
14:54:01 [Abgleich mal_conduit]
14:54:01 Connecting to AvantGo: sync.avantgo.com
14:54:11 Connection successful
14:54:12 Connecting to AvantGo: sync.avantgo.com
14:54:18 Connection successful
14:54:18 Invalid login.  Please check your username and password and try again

Since the MAL-Conduit uses the settings on the palm, I tried to sync with the 
AvantGo server via my mobile phone (GRPS) to check if there's the same error. 
Well, syncing via my mobile phone works fine, so there must be a problem with 
the MAL-Conduit. Anyone experiencing the same error? Any solution available, 
yet?

Thanks.
Jörg
