Opening A Dtg Scenario Timetable

Hello,
I’m trying to figure out the PC editor and thought it was a good idea to open a scenario and check how it’s made. I’ve tried to open the timetable for "A Cornish Circle" in West Cornwall Local (Penzance), but it’s not opening when I double-click on it. So I figured I’d create a copy and check the copy. But when I open the copy, the Editor crashes with the following stack.
Is it an expected thing? We cannot open DTG scenarii?

I did try with another scenario on another route, and same result.

 

You can't without decooking it, which in the official editor can't be done but with the editor mod it can.

Hello. Thank you for your answer. I suspected something like that. This utility really needs a FAQ (from DTG or us)

 

Unfortunately DTG are lacking on documentation and have for years.
