Can't start campaign. Details inside.

[Socy]

Since nothing seems to work I'll try a complete reinstall, RTW and everything. I will keep you informed with results. Hopefully the problem will disappear. Thank you all for your help so far :)

Tried to reinstall and it didn't work. Custom battles works fine but everytime I try to start a campaign the game seems to be loading only to throw me back at the singleplayer screen. Tried deleting the map.rwm once more. Would really appreciate help :(.
