Hi guys and happy new year to all
Having exactly the same pb on Win7 as Nikoagonistes
when launching Casusbelli I solved it after realizing I had to create the missing "Mods" directory myself in the Electronic Arts/Crytek/Crysis Wars
tree and place the "casusbelli" directory into it.
Then the system did the rest as joeldecaroual
Hope this can help
thanks again for the job I'm looking forward to try the game !
