I have noticed that the program sometimes mixes upp char belt files.
I couldn't logg on to my alt account anymore(or i could logg in but it freezed after klicking logg in on the char), so i thought:
hmm.. what's causing this?
And after i deleted the belt files it all worked perfectly again:)
I hope this is of some use to people that can't use the client.
Great client Ender, keep it going:)
