LiveCycle has unhandled win32 exception

Hi, Everybody.

LiveCycle was running fine when I logged out last night.  This morning opening last nights file produced a "unhandled win32 exception occurred in FormDesigner.exe[5864]. and asked if I wanted to debug.

When I selected NO, LiveCycle shut down.

When I select yes, the message from Visual Studio was

First-chance exception at 0x004a50cb in FormDesigner.exe: 0xC0000005: Access violation reading location 0x00000000

I'm running XP Professional x64 Edition SP2.  There should have been no updates overnight, but after LiveCycle didn't work I rebooted and there were some updates.

Any one know whats going on here?  I need this program!!

Thanks!

Kay
