The shelves do work, I downloaded them.

I've got two problems so far...My pets drop microwaves all over the place, and while my Sims can drive their cars, they can only go alone..If they try to take anyone..They just stay there in the car..Unable to leave..Or drive..

Anyone have these problems?

I think that one was chalked up to an out of date InSim.

I removed the old version, but my Sims still can't carpool.

This problem was discussed earlier in the thread, you need to update insiminator.

Then you need to go to MTS2 and follow the help walkthroughs there and if they don't work, post a thread there. This site and this thread are not for technical help. The thread was created to let people know what hacks didn't work with pets.

I have the latest version of Insim..And no, the topic has not been raised here, as I have already checked....Also, I know this has something to do with a hack, so I'll have to do it the old fashioned way, and remove hacks till it works again. Oh well.

Sorry, I was just referring to the microwave issue, I mistakenly quoted both. It was a known problem with the old insim that reproductive adjustors (shaped like microwaves) were popping up whenver a pet peed. If you don't have the old insim, then I can't see why on earth microwaves would be popping up. Have you tried clicking on them to see what happens?
