I am having trouble getting my Home Patrol 2 Scanner to update using the Sentinel software. When I try to update everything, I get the error message " Updating HP failed. Operation is canceled. The operation has timed out. I have tried to email scanner master, and they told me that I need to make sure that it is showing up with a drive letter, which it is. If the issue is when you are trying to download the database, then it might be a firewall issue. try disabling the firewall, or creating an exception in your router. How do I do that??
