So, I wanted to buy the Garmin GTN 750 for X-Plane 11 so I downloaded and ran the E-Commerce installer, entered in my Flight1 login, information and credit card but when I click on the "Click Here for Secure Purchase" it seems like it is beginning the transaction but then nothing happens, for some reason the transaction won't go through, I even tried once with the Paypal payment method but that wouldn't work either.  I would really appreciate any help, thanks.

Nevermind, I figured it out.  Was my anti-virus blocking the transaction.  Once I added the .exe file of the E-Commerce program to exceptions, it worked fine.
