Soulsilver File Invalid Save File

[CaptureTheDarkness]

Well. I hope I got the right topic and all, if not I am very sorry. 
Let me start with the basics. It's an original cartridge, played a lot on it. I'm not very sure but i think my sister and her friends used an action replay kind of thing on it. but it worked after that.
A time ago I wanted to play it again but it always told me something like your savedata could not be accessed or something like that. 
I tried a lot but nothing worked. I can't even reset the complete thing. It is just stuck like that.  

So i tried different methods to try and save it somehow. 
I dont know if there's anything on this file but pkhex won't open it and says ''invalid save file loaded aborting''
I obviously need help... is there something on this file? is my game forever lost? I tried an older version of pkhex, the newest. Nothing.
