Didn't change anything unfortunately =/
*edit*
it says synchronizing with network now but nothing's changing (just randomly happened though wasn't caused by changing firewall settings and stuff)... is there anything else I could do (using the console for instance?)

*edit2*

here's a screenshot of my debug log, maybe this helps somebody who's a bit more familiar with this stuff than me?

It is stable (not increasing)

Hey guys!

So, I downloaded bitcoin-qt 2 or 3 days ago and everything went pretty smoothly so far but now out of the blue it keeps stating that apparently there is noo "block source available" so I'm stuck at "22 weeks behind" now which is a real bummer :/. I do have "8 active connections" to bitcoin network though but nothing's happening.

How do I solve this? HELP!
