Is this your game, or are you playing someone else's game?

If it's yours, please upgade to a more recent version of AGS. It's not really possible for me to debug v2.56 now (bear in mind that version is 2 years old now).

Can i update my game to that version without having to change alot of code?

Make a backup and try.

If you run into problems, you can try upgrading one version at a time:
