We've had issues regarding the save game disappearance in The Amazing Spiderman. Well, I've found a way to make it work agaun, but i've only done it in my computer so I'm not sure if it really fixes it.

Note: I did this on the pirated version by Skidrow so it may not work on original game. Also, i did this on Windows 7

How to do it:
Step 1: Open  C:\Users\YourUsername
Step 2: Adjust folder settings to make hidden folders visible. If you dont know how to do it, Google it. A                   new folder "Appdata" should appeear.
Step 3: Open AppData\Local\SKIDROW\212580
Step 4: You should see a folder names "Storage". Copy paste it in the same folder for backup.
Step 5: Open the storage folder. There should be a file named "asm_save.fpop" and some other files too.                   Delete all files except "asm_save.fpop" making it the only file in the "Storage" folder.
Step 6: Open  C:\Users\YourUsername\Documents\Activision\ASM\Save
Step 7: The should be a file named "asm_save.fpop" too. Copy it and paste it into your "storage" folder form             Step 5.
Step 8: Open the game and your save game should reappear.

The above procedure got my save game back so it might get yours too. Try it.
