Enable the debug cheat (
Ctrl + Shift + C, then type
boolprop testincheatsenabled true) after your game finishes loading, then try entering a lot. If an error box pops up, make note of the name and location of the error log, then select "Delete". If another error pops up, just repeat the above. You should be able to get into the lot afterwards.

As for the error log, look for it in your
C:\My Documents\EA Games\The Sims 2\Logs folder, and attach it to your post. I'm sure someone can decipher what might be up after taking a look at the error log. :angel:
