TECHNICAL SUPPORT / WEB APPs BUGS

Okay, so I have an old account and was created before the server merge. I subscribed and unsubscribed before the server merge, and I had a long break so I had no idea what changed in the game. Currently, I have a new free-trial account. If I resub my old account, will I get my character back? (I know I won't get my gears back) Also, my new account and my old account have the characters with the same names. Will this cause problems?
