Game doesn't change when I insert a .sol game data file

[TheAlphaLeopard]

Describe the bug

I have tried in multiple games (ltf3, madness project Nexus, etc.) and none of them read .sol data properly. When I download the .sol game data file it seems like it works but then later on when I try to replace the current .sol file with my downloaded one nothing changes and all of my progress has been lost. Is there anything I can do to fix this, or anything you could do, because I REALLY wish my games truly saved.

Expected behavior

I expected just to be able to download and then replace the .sol data but it doesn't work
