Hi all I was forced to revert back to windows 7 32 bit after a faulty DIMM was causing constant blue screen errors(had to downgrade to 3GB of system RAM). I had to redo my whole system again for 32 bit. Now when I load my worldspace esp I was working on in the CK it gets to 96% and the little blue circle just perpetually spins and it wont load. Now heres the thing, it loads fine in skyrim game and everything is as it should be except all the enemies I placed are missing. Can someone help me out here please as I can no longer work on my mod till I get this sorted. Thanks

A 64-Bit OS can work with <= 3GB RAM, FYI, so you *didn't need to reinstall Windows. A 32-Bit OS can only utilize roughly 3GB RAM, however, even if more is present. Could be you're missing assets which those _NPC forms (ActorBase) require after the reinstallation? Also, depending upon how you installed Windows over your 64-Bit, previous installation, your old Skyrim directory might be intact within Windows.old\Program Files (x86)\Steam\SteamApps\Common\Skyrim. If that's the case, you should be able to easily reclaim said missing resources.

*you might be able to rollback to your previous Windows installation in which case your Skyrim should also revert.
