I just got M&G tonight. After I installed it and clicked on it to open I got this error:

Does anyone know what this means or what I can do? Thank you.

Yes, I have FT and AL. I don't know why it's happening. I know it is the bookcases though. I was playing a house that had a maxis bookcase and it was just fine. Then after I edited the bookcases, I went into the same house, deleted the maxis one and put in one of the edited ones and that's when the problem started. After I deleted the bookcase and put the maxis one back, it was working just fine again.

Ok, so I followed those steps and when I checked the bookcases in game, they did have all the new options. But...all of the ones I updated are freezing my game. If I have one of the bookcases on a lot, it freezes, my sims won't move. But I can go into buy mode, delete it and then they start moving again.

Sorry for the necromacy, but I didn't want to start a new thread. I am trying to update my bookcases, and I got this part done:
How to update OBJD:

Object Data > RAW Data > Select Decimal

07. Resource cross-refs > Interaction Table ID  1 -> 3

Commit and save.

But I don't know what I should be doing with the updated resources I downloaded from Lord Darcy.

Thank you sooo much!! I had NO idea you could do that!

Ok, I have what is probably a very dumb question, but I can't figure it out!  How do you extract the .package file from a sims2pack in Clean Installer? I have tons of sims2packs and would love to delete them cuz they're taking up so much space. But I've been saving them in case I ever had to reinstall them. But I would prefer if they were .package files. Again, I'm sorry if this is something really simple!
