No unused FET found

Hey,

I’m trying to use CLion with PlatformIO Plugin and using there a MSP430FR4133 to work with it. After several hours, I got that far, that I got this Error Message “No unused FET found.”.
I googled, and all solutions went to a driver I have to download, but all of those links are not working anymore, and I can’t find a solution. I’m on Windows.
