You guys should be creating separate posts. The routes to a solution could be quite different.
Greg, it sounds like you questioning whether you should try an IPTV Reset. If you haven't tried it, the answer is "yes," try it. It doesn't hurt anything and often gets things working.
Suvan, did you login to the Donation Checker to see what it had to say about your account? Does it indicate "active?" It can take 24 hours or more before you account becomes active. Also, you need to make sure the transaction was completed. Sometimes the credit card declines an international transaction. Your card has to be capable of making an international transaction. Many do not.
It would also be wise to report the add-on/app you are using.
