Moved Subsonic to new server

Hi,
I moved my subsonic server to a new Win7 machine and updated to the latest version at the same time. Now, I can no longer play music via a browser outside of my network. First, I copied the entire C:\subsonic folder from the old server to the new. When I experienced issues with that, I decided to revert back to the subsonic folder that was installed with v5.2.1. It was like setting everything up new, which was really starting to take a lot of time. I wanted to keep all the user accounts, so I copied over the database from the C:\Subsonic\db folder. At first, I thought that did the trick as I was able to access the server and play music (while I was on the same network). Now that I'm off the network and trying to access it from the web, I'm experiencing the same problems as i started with (none of the players will play within any browser).
Does anyone have an idea of what to try next? I'm at a loss.
TIA
