I found a (temporary?) solution that seems to be working for me (for now):
Delete EVERYTHING out of the /temp directory and re-log-in to Max.
I think users may have to think about doing this more.
What instead, many say to do, is a clean uninstallation. Well, that also removes those files/folders when done correctly as instructed.
Plus, it uninstalls the whole program, and then you have to install again. Although the uninstaller for SF does completely remove what's in the program folder for Streamfab.
But it does not clear out the extra folders, more likely, so users don't then have to log back into all their providers each update.
But as I said, I think they know and have some idea of the crap that builds up in the temp folders and should make better attempts to remove it, as over time it can cause issues.
Locations of other foldersEITHER use%HOMEPATH%\Documents\DVDFab\StreamFab\
%HOMEPATH%\Documents\DVDFab\StreamFab\Log
%HOMEPATH%\Documents\DVDFab\StreamFab\Temp
%HOMEPATH%\AppData\Roaming\DVDFab\StreamFab
or use%USERPROFILE%\Documents\DVDFab\StreamFab\
%USERPROFILE%\Documents\DVDFab\StreamFab\Log
%USERPROFILE%\Documents\DVDFab\StreamFab\Temp
%USERPROFILE%\AppData\Roaming\DVDFab\StreamFab
Again, SF should clean up after itself, as even deleting the whole temp folder requires at least the user to re-log into their providers.
The clean uninstall, if users don't save the streamfab.ini file before, they also have to set up the settings in SF again.
I use other programs and now found out that one of them requires clearing out the cache for it, if/when it starts having issues.
