I'm sorry you are having troubles.
If it's any consolation we are going to be simplifying things in the near future.
So your struggles are in some ways helping others in the future
Having said that, I hope you will bear with us and not give up so that we can learn from your troubles. If you don't give up I will help you until you get it figured out - you can always email me (
[email protected]) for help.
1) When you visit that license key page (
https://www.donation...r.com/Keys/index.php), it should recognize you by your forum id, as shown in the first picture, and offer you some license key links. If it doesn't, perhaps you have cookies in your browser disabled and it can't recognize you? If so, you need to turn them on!
2) After you click on one of those links you should be given a nice long license key starting with *r1... As the instructions say in the second screenshot you just select this and copy it to clipboard, then go to the about box of the program and click the button to enter the license key.
See screenshots for more help. And let me know if you get stuck.
