Yes, I have plenty of special characters (pwd is generated by a pwd manager)
Alright, I am going to assume it is the special characters causing issue then. If you don't mind, could you either generate me a new password with the same special characters, or send me your password shuffled (you could use a website like String Randomizer or just copy and paste parts of it around like 'thisisatest' to 'estsathisit') and send it to me in a PM. That way I can verify the problem by changing my own password and then figure out a fix pretty quickly. I guess quickly though, does it have an '=' or '+' in it?
