coolant not working after upgrade

[mark c]

I'm having problems getting my coolant to work again. The timeline:
Last Saturday everything worked well using V1.9.084. Monday I updated to V 2.012. The coolant no longer turns on with m08, CRTL-F or clicking on the coolant button on screen. The only time it will come on is related to the RESET button. Now it goes on only when in RESET; changing enable to actvie low turns coolant on unless in RESET. THe coolant command changes nothing except the related led which lights up correctly.
I'm using the supplied 1024 screen set.
Can anyone give me an idea about what could be going on? I've switched ports, settings, active hi/low etc. I'm at my wits end

Have you changed the active low of the reset?
