Script program status is "Loading" after upgrade
Upgrade Script Program
A new keyword may have been added to the new version
A new keyword may have been added to the new version, for example the word "Debug" can be used as internal variables in script programs up to v1.3, but not in v1.4 onwards. In this case simply change the word "Debug" to Debug1" and all works fine.
