"Save not compatible" Error

[Salticus]

So, i used GameData switcher (I have used it before and everything worked!) to switch on stock, everything worked (I wanted to try something only stock) and then I switched back to my normal Gamedata with very many mods. When I open "resume saved" on EVERY Save there is written "save not compatible" (translated from german, dont know if it's like this in english). When i click on it and want to resume, there's a window saying "This save is not compatible with this version of KSP, do you really want to resume?", even no Update happened in the time i played stock, if i click OK in the top left corner it writes in red text "following save cannot be loaded: *save name*" Please help, right now it seems like my whole progress is lost. Btw, the scenarios can be played, but if im in it I can't click the buildings like Tracking station.

 

Edit: The saves where all empty. There were no ships, nothing other than the folder "Ships". I then used the saves from an other gamedata, now i have my progress back (Not all, Like a few ships aren't there, because i used this gamedata a while ago, but at least i can use most of my saves without loss of progress) But i would like answers how to solve this, because some other people have this problem to and there was no solution to this, and because i could have the problem another time.

Any backups?

Go to the .sfs files of your backup and copy those into the presistent.sfs files.

WARNING: I HAVE NOT TRIED THIS. IT MIGHT BREAK THE ENTIRE SAVE

Luckily i found out that game data switcher has for every game data own saves. So i used the ones from an other gamedata, everything was there, I only lost 1 ship. And my last real backup is about a month ago.
