Description
An old smaller POSREG.VR file was loaded onto the controller. The number of position registers 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 position registers to the necessary size again. But a cold start is needed to increase the position register table size. Do a cold start.
