CAP Demo - ♦ Issues & Solutions Here ♦ - New CAP Demo Available - See First Post

I found a solution for the problem. Hope you have a backup of your gamedata!
So at first I wasn't able to start my Sims game after I have installed that demo. After uninstalling it my game still crashed.
Then I restored the DCCache folder from a backup and everything is back to normal! :D

So that ******* demo irreversibly malforms the installed cc databse!
