Dose anyone have and idea on how to fix this? The addon was working perfectly before today. I only recall moving my addon folder, rather where I store my downloaded addons before installing them
You should seek support from the addon’s author rather than these forums.
Why are you telling me something I already know? extreme pbr is extremely famous and alot of people use it. the fact that I checked everywhere on the internet for people having the same issue but didn’t find means it’s something I moved or did without thinking. I posted on are thinking I’d get some sensible info but nvm
Right, but you moved stuff and broke it. Have you tried moving it back to see if it works again? How are we supposed to know how to fix something that was previously working. That’s like opening up the hood of your car and ripping a bunch of wires out then telling the mechanic that it won’t start. Yeah we know! 
you didn’t get the post. I didn’t move anything important I simply moved the folder of my downloaded plugins not my “main” plugin folder in blender. it’s like moving a game installer from your documents to your desktop and that makes your game not open again. Anyway I already fixed it. for some reason windows itself was putting a question mark before the location idk why. like instead of \C:\blender\addons\etc . when I check certain textures properties panel it was ?\C:\blender… don’t know why and how the question mark got there. do you have any ideas as to why this happened? it worked fine when I exported else where
