I cannot change game directories to D:

"
it doesnt allow me to edit the game directory
 
 
"The game directory you attempted to set has been locked by the current configuration, and has been reset to the default directory. If you're using a Gameband + Minecraft, please use a directory on the Gameband."
This makes me so nervous
 
All my files are on D: than the launcher itself!" Quote from discord.
 
"I cannot use my microsoft account on feedback.minecraft.net
 
 
so I came here
 
 
When I launch optifine, "Internal error. Preparing OptiFine-1.8.9_HD_U_I7.jar Name: Preparing OptiFine-1.8.9_HD_U_I7.jar Error details: HTTP 404: Not Found"
 
Or just 1.12 "Internal error. Preparing 1.12.jar Name: Preparing 1.12.jar Error details: HTTP 403: Forbidden" Another quote from discord. Not going to repeat!
Yt vid already 3 day late because of the bad support they gave me on discord #support!
