If you are having this problem, you:

  1. Have not uploaded the .htgcplicense to your ROOT game cp folder (i.e. /gamecp/)
  2. When you downloaded the file from your email attachment, make sure when you are at the SAVE AS window, you select “all types” and not just “text file”. Select “All Types” and then save it to your desktop or where ever.
  3. If you have done both of the above, check to make sure that you only have one instance of the .htgcplicense file. Make sure its only in your ROOT gamecp folder, and not in /gamecp/includes/ or anything like that!
