After updating to Service Pack 4, Vectorworks will "lose" it's internet connection. I have checked all firewall and virus programs and they are all correct. If I run the Repair feature in Vectorworks Updater it will repair (1) file (never says which file), then reboot my computer, it will function normally, for a time. Then at some random point it loses it's connection and will not download resources. This is quite frustrating and time consuming. I'm reluctant to perform a clean install as I have multiple add-ons and customizations. This didn't start until the SP4 release. Thoughts?
