Login Failed cant get in

I just updated OS from VISTA to W10. Been running Soulseek QT for a long time with no hiccups. On reinstall, a box keeps coming up that says the following:

"Login Failed: The password you supplied does not match your username. Please change your login settings in the Options tab and try reconnecting."

I tried doing that several times but keep getting the same error. Can someone help me to get back on? Thanks.

looks like it's what it tells you: the SLSKqt Name + password is not the one you created it once.
here's a bit deeper Info how this problem will solve itself in about 30 days:
