replaced exe and sims 3 world advetires keeps crashing after loading screen

[simpleprincess]

I did as follows..

The Sims 3: World Adventures v2.3.33 [MULTI18] No-DVD/Fixed EXE
File Archive [3.6 MB]

Play Instructions:
•Install The Sims 3 game - Full Installation.
•Install The Sims 3: World Adventures Add-On - Full Installation.
•Apply the official The Sims 3: World Adventures v2.3.33 [WORLDWIDE] Patch.
•Replace the original <GameDir>\BIN\TS3EP01.EXE file with the one from the File Archive.
•Play the Game!

If I go to the bin and click on ep1 it goes as far as my family and goes to load them then says microsoft has encountered a problem and needs to close

If I click the sims 3 exe it doesnt even start.

Im really stuck now as im worried ive messed it all up I replaced the host thing as well as it instructed to do it

im sure I installed the patch.

Im baffled and im sorry if its in the wrong place im not used to this forum and couldnt work out where to post.
