Sims LL and House Party Problems

[Syndra]

Hi all...I am hoping someone here can help me...I have all of The Sims games expansion packs, you name I got it...I love the game...Here is the problem. I bought a new computer last year with ME on it...I can get the The sims, Hot Date and Vacation to work..But Livin Large and House Party refuse to work at all...It says it installs ok and I get as far as the laoding screens but then it just dumps to the desktop..I have tried the patches, no patches, just one game then the other..I am very frustrated..Please Help Me..
