VC Crystal not taking my save anymore

[iChaos92]

Hi there

Dumped the save from my VC Crystal with Checkpoint (v3.7.4) and edited some stuff with PKHex (v.24/06/03). Moved it back to my SD in the same folder as before and tried to restore it again with Checkpoint. There, I get a success message (that it was successfully restored), but when launching the game, I get: "The save data is corrupted and will be reset".

Which is weird because the save file seems to be alright - when I re-dump it and open it with PKHex, it does show all the content.I am also doing the same with my USUM save a lot - no issues there, this works smoothly. I also remember, that I did the whole thing earlier without any problems.

I am wondering what's the issue here? I've uploaded the save here, so I hope someone could take a look! Would be much appreciated

Btw: has the SecureValue-file (this gets dumped from Checkpoint with the save as well) something to do with it?

Many thanks for your help!
