This would be something better served over on the Tech Support sub-forum, as it would not be an Account Issue.
Good luck.
Sorry but you wrong! Because I have 2 accounts and only this have problem and not other and have tried with 2 different pc so it not computer or hardware problem.
If you are experiencing a 7:11:3:191:101 error or something similar, you will find a thread over in Tech Support with Dev responses, and possible helpful advice.
If you have some other issue, and do not want to take advantage of the Tech sub-forum, you can submit a ticket to CS. There is little the Account Issues sub-forum can do for you.
Good luck.
