Deleted website, can't login to FTP

I did the exact same thing - Thought there was a virus or something causing my webpage to not load. After deleting just the files on the FTP side, I tried logging back in to re-upload the files and now I can not connect in to the FTP site. I am getting a “Login authentication failed”. Tried several FTP software programs and also tried logging in to the File Utility in the control panel. Get a password error. Tried changing password and get a " Validation error" The password may only contain letters and numbers. -
