Go to the following location and path, and manually delete both the “Daring Development” and “Infinity” folders, if they are still there.
C:\Users\Your- Windows USERNAME\AppData\local\Daring Development, as well as C:\Users\Your- Windows USERNAME\AppData\local\Infinity.
Look for the ROAMING folder as well, under AppData. Remove the CACHE, or the entire daring development and infinity folders…
These folders can found under “Roaming”, e.g, . C:\users\Your username\AppData\Roaming\Daring development\Infinity\CACHE.
And, C:\users\Your username\AppData\Roaming\Infinity\CACHE.
Check this installed path as well, i.e. C:\Users\Your UserName\AppData\Local\Package cache{some random numbers} folder, if this has been created.
Try to re-download/update INFINITY from this link. Restart your OS, and try to log into the app once again:
https://s3.amazonaws.com/wemod/infinity/releases/master/Infinity-Setup.exe
The APPDATA folder and the associated directory might be hidden by default in most of the Operating systems, so you won’t be able to find it.
You need to enable this option, “Show hidden files, folders, and drives” under the ‘File Explorer options’ setting, via Windows Control Panel.
If you don’t want to delete the entire folder under ROAMING, then just remove all the .BIN files located here, e.g., C:\users\Your username\AppData\Roaming\Daring development\Infinity\trainers.
Depending on the game, the numbers might change, e.g, 61-1477409811.bin, or 144-1476900945.bin etc etc.
Try a CLEAN re-install and update of the Infinity software, if need be ? First go to control panel, and remove the software, under “Programs and Features”, and then re-download it.
