password issues

Had forgotten my password when I bought a new computer. Had been using soulseek for ages on old computer.

Now I cannot log in. No matter what I do in the client, it just tells me I have wrong username/password and even if I change them, client doesn't seem to recognise change.

Obviously, as logged in here, I have a working combination.

Have tried uninstalling client and reinstalling, but no love there. An thoughts?

Would really rather not reformat computer.

Thanks
