I've got a database folder from the latest 3.6.1 version of the Offline Compendium and ran it through the Python scripts. I didn't encounter any obvious errors, however the console output is giving me some concern. For NPCs, Feats, and Powers, all entries that were recovered from the database were converted, but other numbers don't match up:
* 631 basic weapon entries were recovered, but only 128 were converted
* 493 basic armor entries were recovered, but only 99 were converted (as Weapons)
* 1963 feat entries were recovered, but only 180 were converted.

Is this intended behavior?
