Hello
I was trying to resubscribe to TNII through the pokertracker 4 client, and paypal.
Twice I went through the purchase process through the PT4 client, and paypal website. Each time it appears to have gone through, but then I am back at stage one "Checkout: Confirm PayPal Payment" etc..
I checked my paypal account, and it doesn't appear to have gone through.
UPDATE
Your checkout screen is somewhat confusing, I finally realized after I used the paypal site i Need to click the paypal checkout now at the bottom.
