Broken os (Patreon)

So I wasn't able to draw for 2 days because I had a broken OS. It's hard to explain but basically drawing became impossible because each 20-30 seconds, the pointer simply does nothing, no trace registered which makes drawing a pain in the ass. I pass my whole Saturday trying to fix, I thought it was an hardware issue but not. I fixed it with a format but sadly I lost a license for a software I use daily and that cost me an extra 100$, well, my fault I guess ? The company stopped the offline validation so my key became useless... Now it's finally fixed!
