I started playing JJ2+ on Turbo difficulty a week ago. Because I ran out of free time, I just saved the game so I can play it later. Now, when I opened up JJ2+ and then opened the save, the game crashed with this error showing up:

What can I do to get my save back? I saved at the beggining of the first Medivo level, if this does matter. Of course, I could easily start the episode from Diamondus and use JJNEXT for a few times until I get back to the level, but I had all the powerups and weapons, except the Zapper (or whatever is it called). Help? :P
