As I see from these pictures, especially the programming list that there are a lot of Ecus to be replaced. you either used a different CAS (Probably), or you are mounting Ecus not compatible.
You have the expert mode in programming, that's why you were allowed to pass to the programming window of this DME, but when Autohex requested a flash data from the server for a specific model, and specific number, the server could not find a match.
This means: The DME you are trying to use is not for this series, so you either have to correct the CAS FA (if you changed CAS), or you must replace the DME with a compatible one.
You are defiantly not doing the job correctly, first thing to do is, checking why too many Ecus marked for replacement, then start fixing the DME.
