Hi 55555stitch55555 I work in a small pc repair shop in central Florida and we have the same problem here a couple of times also. This seems to be a sign of a bigger issue when we see it here. The user files have changed directory to C:\Windows\system32\config\systemprofile. You can verify this by hitting the start button and right clicking say Documents and clicking Properties. Whenever we see this issue we create a new admin user after running an initial scans with adwc and mbam. On the new user the directory should be correct and will now let mbam update. To be on the safe side here we normally just recreate the user profile so that we can verify everything is where it is supposed to be. I hope this helps.
