Guardian Angel support spent almost four hours trying to fix the error in my computer yesterday without success and concluded that something was wrong with my computer. I called my IT guy this morning who found nothing wrong with my server and told me that he just serviced another AC user in my area with the same problem(he was not able to fix it). I uninstalled 6.3.3 and reinstalled beta 6.1.2. Thank goodness, it worked.
I'm staying away from V6.3.3
