Stuck in China, Error Loading Town When I Try to Return Home

I have traveled many times in the sims3 before and this is the first time I have had a problem.  I tried to find a solution on the forums but most people's travel problems have to do with losing a sim or sims when they travel home.  My game won't even let me get home.  I recently installed Supernatural, however, I have already traveled once and gotten home safe since the installation so I am unsure it would have anything to do with me recently installing that expansion.  I am also up to date on updates, just updated a week ago and checked again today to make sure it says my game is up to date.  Other expansions I have are WA, High-End Loft, Ambitions, Late Night, Generations, Town Life Stuff, and Pets.  All of my expansions and the base game are disk versions.  I do use CC.  I was going to try to turn it off but my sims home is a CC and I was worried it would cause more problems getting home to turn it off.  I use a PC running Windows 7.  I can't think of what else I might need to tell you but am willing to answer questions... Please help!

The error messages reads, "A serious error has occurred while loading 'Essymbra.sims3:Riverview_0x0859db43'.  It is strongly recommended that you restart the application."
