I have gotten OOTP to work again!
I uninstalled the following:
Office Live Add-In 1.3
Windows Live Sign-In Assistant
Picasa 3
Microsoft.NET Framework 3.5 SP1 Hotfix (KB958484)
Zone Alarm Extreme
When I restarted my computer, all of Windows, TurboTax and OOTP issues were fixed.
I re-installed Zone Alarm ... everything continued to work except for OOTP.
I uninstalled Zone Alarm, OOTP works. I go back to using VIPRE (which I had removed because of the Windows problems).
OOTP still works!
