I NEED HELP! My sims can't travel anymore!!

I'm not Trey, but the RAM problem is unfortunately not something I've seen any answers to. It's been a problem for a while (and seems to have started with some of the EPs/updates) as I never had a problem with them when I just had TS3 and WA alone (without the updates or EPs that followed.) I too started having those problems with memory (especially in old established families or when I'd done a lot at one time in the game) when I had to reinstall (and couldn't use the incremental updates that I'd used previously, but had to use the update that included all the updates.)

I try to keep a watch out for information about curing the "Code 12" problem but even the non-EA TS3 sites don't have a concrete answer for it. It's theorized that it's due to the games handling of RAM memory, but it hasn't been proven yet.
