I believe I may have found the problem:
In the settings/options it states "Unless you know what you are doing, please leave all items DISABLED (Default).
The 3 boxes you can check read:
DISABLE port check
DISABLE uPnP
DISABLE NAT-PMP
Being that it said to disable them, I checked the boxes saying to disable them.
Going back and hovering over each box, it then said that it was NOT recommended to check the box

Perhaps in future versions, the warning message should read "Please leave these items ENABLED (leave the box UN-checked).
I was going to delete the post, but figured this might help someone.
