Fearless

Hey guys, I just downloaded the latest version of PokeSAV for D/P, but when I opened my sav file from Pearl, nothing happened. This is what I get: As you can see, PokeSAV does display the name of my .sav file but no my Pokémon, ID, my trainer name and stuff. How do I fix this? Edit: I tried to convert but I didn't help. And I also do not understand why my save file could be corrupt.
