I found out my computer system (windows 7 - 64 bit) can only handle so many cs files. What are the cs must have's would you say I should have? I removed all of the cs I had. I'll start from scratch. Thanks.

CS must-haves? That would be ALL the Shy Main Street sets, plus any plants by Old Spice and/or n7, and some of StationJim’s sets. Mind you, these are the rock-bottom basic, minimum, bare-bones requirements. So much more than this is needed to get the most out of your game.
