I have always problems with "Account suspended" when I use the wrong internet browser (for me it is Opera).
Sometimes people could try to use another browser instead.
"Chrome" worked for me, but when I try to use "Opera" it always says "Account suspended". From the first log-in on.
Maybe it will be enough to delete the cookies, but I didn't test it.
I never created more than one account, but I had the same message. So I found out, that it could be a browser problem.
I would recommend all who have this problem to try out another browser.
