I don't know what's wrong with my game. This is the message I get to see everytime I start TMT:

All online related stuff in the game is not accessible for some reason. Can't see times of my friends, can't even open the server list.
Couldn't find anything in FAQs or technical support for the game on the Ubi site. And there's also nothing on the ubi or maniaplanet forums.
I don't have a firewall, all necessary ports are forwarded. Did anyone else experience this issue? Any ideas apart from reinstalling and praying?
