I too am having trouble opening my house after installing the update. I keep getting the following (this is just a small part of the error message I'm getting):

Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000017dd1545
Exception Note: EXC_CORPSE_NOTIFY

For a copy of the complete error message:

I'm on an iMac.

If this is something that's needed to know, I've also updated my Java after I first realized I was having trouble opening my file.
