Regarding your point number 2: The "_xml_" files for your Remote Build Servers actually go into the "build machines" subdirectory under \openmake6\tomcat\webapps\openmake.ear\openmake.war\kb.
A couple of suggestions for your license file question:
- Check your license files to see if the first of them contains any identification as a DEMO license.
- If neither is a DEMO license, compare the line for machine to confirm your Remote Build Server is correctly identified.
Hope that helps.
