Okay, I made it work again.
It seems that the hostslist.txt in the Xolox directory made itself corrupt, deleting & restart doesn't help. It looked like this (only 3 lines posted):
;<?$8>=$;3;$;20<9><
8;9$;;?$>$380<9><
;8=$:$:$;0<9><
I replaced it with one of my old hostslist files, which looks like this (only 3 lines posted):
I;2;>8;2:6346
KI>2;2>8:6347
2?L:;3>;:6346
Try to download a fresh hostslist.txt and make sure it looks like the last one! I'm using Xolox V1.12 - don't know what happened, maybe a bug in Xolox.
Hope it helps, Moak
