Can't get demos

[flowtron]

Thanks jamz - I didn't want to mention it, because he did say "any server", but then again some users often generalize like that ... but it really doesn't explain why he says he can't even run the tutorial-demo - that's seriously weird, if true.
I'd appreciate if one of the demos - apart from the tutorial one (obviously) - was made available, to see whether it's a file issue or the local game at fault.
