I just recently went from windows 10 back to 8.1, backed up my macros and addons/plugins to a usb drive, after the install and updates i pasted them back to where they belong.
Most of my addons or plugins seem to no longer work, i thought maybe was something to do with maybe a difference between win 10 and 8.1 but i deleted the folders and tried to redownload them from the windower launch screen but even after doiing so none of them work..
i get runtime errors and for a few it says no file at the location.
