MW ERROR CODE -8 WHEN SWIPING A CARD

ok. You should ONLY see this error on a new install. It is actually something wrong in the software on the genius. Call MW and they will have you downgrade it to usually 4.1.2 ((sometime this takes a few tries at least it did for half the genius devices at river cats))then take it back to 4.1.10. I’m assuming they accidentally had a bad image that was missing some stuff so we shouldn’t’ see this anymore.
