I think I'll have to check this screen name thing, maybe that's the problem 
(everything else seems to be as it should be).

I also tried the 64 bit version (x86_64) in the meantime, but the problem 
seems to be the authentication, the jobs run with -localonly.

Thank you very much for your help, I'll play a bit with screen names before my 
vacation. I'll let you know how far I got.
