SOLVED: Neighborhood Disappeared

[Coolness]

So yesterday after I compressorized my downloads, my favorite neighborhood disappeared.  I put my old, uncompressed dl folder back in, but the neighborhood is still gone and none of my backups will load, either.  Is there some way I can trick the game into seeing it again?  I've tried deleting groups.cache and the neighborhood manager file.  I've also tried pasting my backup into a neighborhood folder that will load (it's the N004 neighborhood so I've been making the game create another N004 and pasting old files in).

There was an old post on this but is was not very helpful.

Thanks!

Well, I managed to get my neighborhood back.  I figured I'd post how here in case anyone else sees this problem.  Two of my three custom neighborhoods had disappeared but they're all back now.  I removed the entire Sims folder from My Docs/EA Games and let the game regenerate a new one.  Then I pasted in my neighborhood folders (N004, N007, and N010), didn't delete the NeighborhoodManager file, and deleted Groups.cache.  I also put back in my downloads and saved sims folders and a few others.  When I loaded the game my neighborhoods were all there and when I went into a lot everything seemed to check out fine. 

I'm not sure what went wrong, and I suspect that it happening at the same time I used the Compressorizor was more a coincidence than anything else, because my new compressed download folder works well.  Oh well, I hope that this can help someone who might have my same problem.  It was much easier than reinstalling my game (especially since my disks are four states away).
