Forum:Can't connect to my account

I have an account I play on for months, but since last week, every time I try to play PTD with it, it sends me a "Error - The server sent a faulty response. This is due to either the server has reached it's capacity limit, server code errors or you don't have internet." message when the game tries to retrieve my profile.

Said account still works on the PTD mini-site or on PTD2, though, and I don't think the problem comes from my connection, as I tried it with several connections, and they all gave me the same message, so... Where can that problem come from, and how can I take care of it ?

Thanks in advance.
