Problem Login

hello, I have a problem, I have two accounts chesscube. I used one of them facebook login but it was a mistake, the other I had to login using facebook.
The accounts are:

1) augusstin - Facebook Login

2) August_In

how can i change facebook login for the account: August_In ?

i can't login either. i've tried deleting cache/history but no good. i am using firefox browser, please help.

I can't login for playing from yesterday. I've deleted cookies, but it's not helped me. I made 2nd login and it's not working also. I wrote to support but didn't get the answer.
