Hello.

All of a sudden I am having a problem with SimPE whenever I try to edit anything in my neighborhood. When I click save I always get a System.OutOfMemoryException error message. I get 100s of them in a row and all I can do is quit SimPE because it freezes. I have tried everything and nothing is working. I followed the tutorial about setting SimPE to handle more than 2 gigs of RAM, but it never works because CFF Explorer will not let me save the changes. I also restored my neighborhood backup files and still am getting the same problem. I don't know what else to try but I really need to get this sorted out, as I cannot play my game without SimPe. I use it for everything and have never had a problem like this before. Please, if anyone has any suggestions, I am all ears. 

Here's one of the many error messages that pop up when I click save:

Message:
Error while trying to open

Package: C:\Users\MarieJones\Documents\EA Games\The Sims 2\Neighborhoods\N001\N001_Neighborhood.package

Default (0.72.1.33855).

It says windows vista but I'm actually running Windows 7. Also, where it says "File: Sim Relations...", I get messages that say "File: Sim Description.." and "File: Binary Index..." and lots of other things. If anybody knows anything at all, please help and I am willing to try whatever you can suggest. 

Also, if my neighborhood is corrupted, that would be strange because the game plays just fine and I have no problems with it at all. SimPe just won't let me make any changes. Everything else is fine. Thanks for reading

Thank you very much for replying, I will see what I can do. It's strange because SimPE was working just fine on Windows 7 for a few weeks. This problem suddenly appeared. But I will definitely try what you suggested. Thank you!

EDIT: Thank you for your suggestion. I had to play around with it a little and things seem to be working for now. I appreciate your reading this.
