Thanks for the report!

I tracked down the startup issues to two ATRM recipe/prototype definitions. Both have been fixed in ATRM 3.0.3.

The updated version has passed startup and compatibility checks across all six supported profiles, including K2SE.

Please give 3.0.3 a try and let me know if you encounter any further issues.

Thanks again for helping identify this!
