Have been trying in there, no luck so far.
I might just switch to linux anyways. Too many problems and not much support for Windows. Thanks for the assistance though, Thom.
Don't switch yet
First, I had the problem, and like Thom it was solved with some helped. But I know I can find the solution again, and besides, I had the problem on linux
I will let you know the solution as soon as I find where my irc logs are
Edit:
Ok, found it:
open mysql and do 'UPDATE item_instances SET item_stats_id_unique=0;'
It was because of a bug though, which I guess was fixed, so I am not sure you have the same problem.
Good luck!
