Whenever I tried to run GMod, I faced an error message
Whenever I tried to run GMod, I faced an error message which says,
You need to buy Garry's Mod on Stream to be able to play it
At this point the process gets closed automatically. The fact is that, I purchased GMod in 2007.
And since that moment I have never had such a critical problem until today.
I can’t guess what the cause is. Can you?
