So.. I have reset the password and initially used the random one generated that got me into the cPanel but again the domain change script failed with the same error. Then i changed the password again with one of my own but different from the first one and again the same error...
I don't think it's a client side problem but just in case i have tried different browsers and computers with different operating systems.
I have added the domain as parked but i would like to get rid of the co.cc one.
