The Re-Volt Hideout

hello, I recently installed this game and made quite some progress, but now if I open the game I see all the progress is gone. Did anyone encounter anything like this before, and is there a way to get the previous saved files back?

Do you use several profiles ?
When starting the game you are asked which profile should be used.
Perhaps you took and empty one.

Is rvgl have read AND write permission for your profile folder ?

note : move rvgl away from "Program Files" folder to something like "c:\RVGL" ...

This can happen sometimes if the game closes unexpectedly due to a crash/power outage.

Have you resolved this problem, or does it still happen un a regular basis?
