Hello Nabil,
You are trying to generate a scenario from a DVM (fglrun) log file.
From a log generated with DVM 3.00 but using GGC 2.00.
GGC 2.00 has been included in the bundle FGLGWS 3.20 not in previous versions.
Products delivered inside a bundle work together. But not with products from different major version (for example 3.00, 3.10).
If you need that GGC 2.00 supports DVM logs from 3.00 and 3.10 - We invite you to contact your local support centre and ask for a feature request.
Best regards,
Olivier Eckert - Four Js
