The Sims 3 save file won't load and crashes on loading screen

@yankikkie  You have no reason to apologize; we're always happy to keep troubleshooting for however long it takes.

How did you move the sim to Bridgeport?  The in-game option (over the phone) is problematic in that it can transfer data from the old town to the new one, potentially introducing corruption as well.  Depending on what you want out of the transition, there are two much more reliable ways to move a sim.

If you just want to start your sim in a new world with no connection to the old one—skills, career, etc. intact but no relationships with the sims left behind—then the best way is to save the sim to the bin, start a save in the new world, and place the sim there.  It's crucial to quit to desktop and delete the cache files after saving the sim and before starting the new save, because another way to corrupt a save is to switch to it from a different save at the Main Menu.  This tends to impose data from the first town onto the second, regardless of what else you're doing.

If you'd like your sim to "remember" the sims in Appaloosa Plains and don't mind using mods, you could use NRaas Traveler, along with ErrorTrap and Overwatch (for stability and data cleanup), to vacation in Bridgeport and then switch hometowns.  This process is more complicated and may not be necessary for what you want to do, but it's worth mentioning.  If you're interested in reading about it, start here:

Even if you don't want to go through the hassle, adding a few NRaas mods could help make your saves more stable and less likely to corrupt.  Specifically, ErrorTrap, Overwatch, MasterController, Register, and Traffic would all be useful with your collection of expansions.  Let me know if you're interested and would like more information.
