I wanted just to share that my CAW didn't opened after doing complete clean installion for all the sims games (I did it right, I followed these instructions excatly: http://modthesims.info/wiki.php?tit...p:TS3_Uninstall ). Caw didn't give me any error messages, the loading screen just showed up and then vanished.
So I also tried all the things listed in this thread, but Caw still didn't opened. I also tried to play Caw with only base game, but that didn't help at all either. So I was about to do clean install for the 6th time and then patch my base game with 1.19 and use Caw version 1.11.4, but I got it to work! And here is how to:
I deleted the world tool folder from here: C:\Users\my username\AppData\Local\VirtualStore\Program Files (x86)\Electronic Arts
Sorry, I don't have any idea what the folders name is in english, because my folder's name are in finnish, but I would still say that there is no problem to find right folder.
Hope this information helps someone. Sorry, if this was obvious.
