Unfortunately I don't speak German but others on the forum do. So you have a choice of staying in this section of the forum or going to the dedicated Deutsch LW section (click on link.) It sounds as though a firewall or router is blocking you from connecting! Please provide your OS version, Firewalls, connection devices (modem & router) brands & model no.'s, & where you're trying to connect from (home, school, work) You can post the details here & I'll help you or else post them in the Deutsch section. Morgwen will probably help you there. Oh & make sure you have the most up to date version of Java: MRJ 2.2.6 for OS 9.2.2 OR else: MRJ 2.2.5 for OS 8.1-9.2

Don't forget to rebuild your desktop (CMD+Option during restart) after installing new sofw.
