So i bought a few expansion packs ( Supernatural,UL,Diesel,seasons )
And i had base game and katy perry ST installed on .I tried to install supernatural
First and it worked fine. Then i instal UL , diesel and season. When i try the game, it said that there is an unofficial ep and i had to un install it to make the game work okay.i uninstalled each of the ep and still it wasnt gone until i was left with supernatural and katy perry. I try to start my game but it wont load. So i uninstalled the whole base game+ep. I reinstall the base game
And started to install with UL first. It worked fine and then i started to install supernatural.
As i clicked the play button , nothing happened and i went back to home
Page. What to do? Pls help :(

I have a SONY Vaio E Series 64 bit processor 2.30 ghz home basic.
