Launcher doesn't work
 

Two days ago I uninstalled my video driver and installed an older one because the newest version causes freezes/crashes.
Ati Catalyst from 10.3 to 9.12..

But now the RO launcher doesn't work anymore. I can open the launcher, but after I login I don't get the second screen (server list).
Already uninstalled RO and reinstalled but doesn't help.


PC:
Windows 7 Ultimate 64bit
Intel i7 860
Amd Radeon HD5850
4gb RAM
