It’s FINALLY working again. I fixed it by accident. I had (as Micro$oft recommended) an Administrators account and a Users account that I was logged into. Guess what? That users account didn’t have full rights to access all folders or something. That’s all I can figure.
I had an Event error where I couldn’t access THAT log under the user account so I changed it somehow and went back to jut the one account. Don’t ask me how. And NOW System Ninja works.
Before that it was just accessing the temp folders and the Firefox one was always empty.
