HaCreator - Object reference not set to an instance of an object? Please help!!

[xDYX]

Hi, I know this should be posted in WZ help but someone else have posted it before 7 years ago and nobody replied, so I guess I'm gonna try asking this here! Please help me, I'm not a developer, I just want to make the mario map developed by Elem0008 work on my free market :( I'm only playing the server with my fam, and i'm not profiting from any of his awesome work!!

Please if you have any ideas at all, even just a small suggestion please let me know because I've been looking at this for around 2 hours now to find answers but to no avail. I tried to understand the problem as well but it still doesn't help.

Thank you so much for all the help!!
