Two major problems...

[tamriel]

I deleted the char i had for my main and want to assign it to another char and it wont let me, which really sucks and i dont know how to fix it! Also i changed the name on this char and it somehow isn't popping up in the "choose profile" section when i start up the game, my old name is there but that char is a peasent again with no experience or items! help!

You must change the name on webpage AND in-game to the same name for this to work.

Also you can only make fresh chars your new main, not your existing alts.
