Can't open Track SCN in GJED

Hi All,
I'm trying to open Joesville track coming with moddev into GJED just to learn about this tool. This is my setup:

According to tutorials, there's no need to include any other MAS or path, right? But then, I'm getting these errors:



And then GJED crashes. I'de tried adding paths and commonmaps.mas manually, with no luck. Any idea?

 

Gjed unfortunally isn't more supported by studio 397

 

Ok, thanks a lot, I'll stop wasting my time then.
