[Maniaplanet + Tmuf] Couldn't init the network

[reaby]

I'm getting now for 2nd day the same message: "Couldn't init the network" when i try to go playing online (doesn't matter if i try local network or internet play, if it has something to do with network it doesn't work.)

I tried to switch at internet explorer: "work offline" to ON and OFF, but that didn't help.
Rebooting doesn't help and for system specs, I'm running windows 8.

It's the same for Maniaplanet and Trackmania Nations United Forever, which is weird.
Remarkable is that on Steam i hit just 4000 hours played (tm united), i could also mention that i did try to load stadium and valley to maniaplanet

disabling the F-secure's firewall completely did the trick. They must have changed something in the last update.
