fioreit: I don't know if the two are related, but what you describes sounds similiar to my problem with updating endpoints in this thread.

I would get waiting for service and the script would eventually time out. It seems the problem in my case is that the AVG install is for some reason running as the logooed in user, rather than the system account.
I haven't gotten an update from Kaseya on my issue, either. Please keep us updated on the status of your issue.
