my pokemon soul silver game corrupted and all of my pokemon that were in the pc disapeared. is there any way to fix this. if there is pleeeeeaaase tell me

I don't think there's a way to return your Pkmns in the PC. It's like a Computer virus:when it enter in the system,if it cancels the datas,the only thing to do is to re-install Windows,or Mac,Linux etc...In the same way,you have to re-start your game from the beginning. I'm sorry...I understand your delusion.
Probably it was a case,your SoulSilver isn't really ruined (it's too recent,except you put it in a wet and hot place).
The same thing happens with my Crystal:it succeeds no more to save my datas.
If your game is really ruined,search for second-hand games:I bought a DS on this,and it's loyal and with no one problem! Hope to help you. ;P
