Hi I paid for and installed amp on windows. I then installed MCMYADMIN. It wont run:
No valid AMP licence was found. Please run
ampinstmgr reactivate minecraftvanilla to reactivate this instance.
I dont have a PHD in computing, so it would be good to know in laymans terms why this has not worked and how I fix it, for instance where exactly do i run this command?
