The $0502 error is common and could simply be a symptom of your not having configured and programmed any BBX functionality to your FlashScan v2 device (which is supported by the Option.txt message you're getting as well).
Use the EFILive Scan and Tune application to configure your device and BBX Options (be sure to select the controllers in the Tune section). Then 'Program' (by clicking the 'Program' button) those settings to your FlashScan V2. That will copy down the scripts necessary to support your configured controller selections.
