did you try making a new LS so that you could at least tell if it's not some sort of file setting/client side issue?
I'd consider this first...
Right now, there's no way to change LS passwords period. So I don't think it matters if you got hacked - you could still log in. unless they also hacked your forum account I guess... there is a thread about LS passwords here which you might find relevant
