Description
An old smaller SYSMACRO.SV file was loaded onto the controller. The number of macros was changed to fewer than what the current version of M.H. Shell needs.
Remedy
M.H. Shell logic has automatically set the number of macros to the necessary size again. But it needs a cold start in order for the macro table size to be increased. Do a cold start.
