I am very sorry that It took me so long to get to this, I just started a new job, so I have been very busy.
Here is what you need to do.
You need to find out what PORTS are being used by that program.(Contact them, or they might have it on thier web page)
After you find out what ports are being used. You MUST set your PC to a STATIC IP Adress (let me know if you need help with that)
Then go into the router, and FORWARD those PORTS to the IP Adress that you assigned to your PC.
Then you should be set to go as far as using that program.
Now if you are having some one grab files off your PC then it gets a little harder.
Do the same as above, then you need to cantact you ISP and ask them weather or not they assign your IP adresses, STATICLY or DYNAMICLY (Cross your fingers that its Static) Then give that ip adress to whom ever is trying to connect to your PC.
