Cant log in? [CLIENT]

For some reason when I try to log in it just says "Invalid username/password combination. Please try again". This does not sound like a problem but I have tried over and over again to log in using all my password variations but none of them worked, I was able to log into the website to make this post so I'm guessing the password is not an issue, and I have tried to reset my password but I have been waiting for about an hour already no e-mail, same thing with the forgot username option, so I don't know what to do
