I can't login to my account in-game since last Friday, after I had a crash in a friendly match. The game loads normally but when I press Enter the game takes a while in the "Cabalvision Spell Channeling" message, followed by a quick message in red saying "Internal Server Error". I've already tried to verify corrupted files through Steam and uninstalled/re-installed the game, but the error message remains the same.

My coach name is "Frankolino" and I have more than 1700 hours logged in-game, and had never experienced such problem. I play in several leagues and would like to please have some solution suggested as soon as possible.
