It won't function in the updated game properly, you would have to manually transfer over the data within the save file.
You could also just, enable debug, and move yourself up that many floors. How to do so is in the documentation.

But I would recommend just playing it through, as much has changed from version 1.0 to version 2.0.

oh also forgot to meantion a game crash/

here's the log it gives me:
