4.4 is out of beta. You should uninstall SS, delete the C:\Subsonic directory and start over.
Here are the guidlines I use. READ ALL the material af few times to get an understanding of what you're doing. Take your time. It is complicated for a newbie, but it is doable, and you'll learn a lot about your system and networks in the process that will serve you well far into the future. Don't try to get it done in a hurry. Take your time and enjoy what you're doing and you'll have a much better chance of getting this set up properly. I have 3 SS servers that run 24/7 - rock solid - never crash. Here you go:
Start with a fresh Java install to the latest version. If you have Java already, uninstall, then do a clean install of the latest version. If you use a 64 bit browser be sure to get both 32 & 64 bit Java.

Disable any DHCP services in any VOIP equipment or other additional routers you have. Only ONE router/device per network should handle DHCP assignments.
Most problems are due to improper setup on the router. Setting a fixed internal ip address for the server and proper port forwarding rules on the router are essential for long term stability.
Never use port 80 or 443 - ISP's often use or block them and these are also the default ports on WHS for the remote login page. 8080,8081, work fine. 808X always works. I've seen others use different port numbers that have caused install failures.

In Subsonic Settings/Network - UNCHECK " Automatically configure your router to allow incoming connections to Subsonic (using UPnP or NAT-PMP port forwarding)." make sure to hit the SAVE button, you may have to scroll down to see it depending on your screen size. UPnP or Plug & Pray works sometimes, but not very often and you're better off learning what's going on anyway. You're dipping your toe into the network mgmt. thing anyway, might as well learn what's going on as home networks don't get simpler as time goes on. As your network gets more complex, you're going to have to learn this stuff! No time like the present.
Manually assign a fixed intenal IP and static route to your server at the upper end of the address range of the router, out of the way of DHCP, e.g. 192.168.1.254
Set up your router manually. uPNP might work, but most often it doesn't. Learing how to do it will be a skill you'll love having as your network grows.
Check the Subsonic Control Panel to make sure it's using the right port you're going to use. I typically use 8080 - 440, 8081 - 441, etc.
Set up port forwarding in your router to direct traffic on the selected port to your server. Consult your router documentation to do this, they are all a bit different.
Learn your external IP address assigned by your ISP. Go to
http://www.canyouseeme.org/ enter your SS port number and click the Check box to be sure the Subsonic port is open.
Test your setup by entering your external IP:port# to see if it connects. e.g.
http://x.x.x.x:8084/ If it works, you're good to go.
