Compiler Errors please help

I'm attempting to install Marlin on a CTC Dual fitted with a MKS Gen L board but I'm in trouble.

The printer has 5 stepper motors one each for the two extruders plus one for each axis.

The compiler is returning :-

SanityCheck.h:1607:1: error: static assertion failed: DEFAULT_MAX_FEEDRATE has too many elements
and
SanityCheck.h:1606:1: error: static assertion failed: DEFAULT_AXIS_STEPS_PER_UNIT has too many elements

Now both have five elements one for each stepper so the number of elements is in fact correct.

Any help would be much appreciated.

Thanks All. Aamcle
