Error: Could not compile. Please review your code

Been away for work for awhile… Have a spark core working on a january project. Now I ordered new cores and want to duplicate the code and create new codes for thoses devices with minor changes… I get a Error: Could not compile. Please review your code.

Funny thing I copy everything in working code, in working code if I CHECK it respond Good work, copy everything into a new file and error message Error: Could not compile. Please review your code.

There’s some changes to the Firmware build version since Jan 2014.

What is the error message? We can advise on what is missing or the issue with the code.

Thanks! :smiley:
