Macro was compiled with a different compiler version
Cause : This message means that the Macro compiler used by Q++ was modified in a recent update, and that you should recompile your Macros to make sure they are still compatible and optimized for the new compiler.
Consequences : Q++ will not let you preview or generate a diary until this problem is fixed, at least for the Macros of the current script.
Solutions :
•Re-Compile All Macros (recommended) : Re-compiles all the Macros in the shared database.
