Old Icecrown characters problem

I've recently restarted playing WoW on Warmane after almost an year, but I can't log in with the characters I had back them.

I mean, they're still there at the charater selection menu at the start of the game and in the Barracks section in the website, but they simply lost their names and I can't perform any action on them, neither ingame nor in Warmane website, they're shown as "no name" characters in the Barracks.

I've tried character restauration, but as I said, their names aren't available for performing any action besides seeing their mere existence in the Barracks section or in the realm logging section in the game.

Any suggestion on what I could do? (Sorry for the bad english btw)

When you try to log the character, you should see a rename window pop up. If it doesn't, there might be some addon or mod that messes with rename window.
That is if I understood you correctly and your characters are tagged for rename due to inactivity.

Ooh it worked now thankfully! I was selecting the character and going straight into "Enter World", then they couldn't be logged. But now I simply double clicked the char and the rename window popped up, thank you for your reply
