I don't know why. I changed nothing with my cards. No tweaking with the cards. I'm good with the default settings. But every time I use TRM, my pc always says that Teamredminer.exe is blocked from accessing graphics card. I'm using 18.6.1 for my vega 64. If I use other miners, I don't encounter this problem. What could be causing this?
Make sure to exclude .exe file from your antivirus or windows defender and then you will not have problem.
Thanks for responding but I already had exclusions for TRM. That's why I wonder what caused this because I don't have this problem if I use other miners.
