Castle Link problem

[Semi Pro]

so i was excited to see that castle had added rock crawler mode to the castle link V 1.23 to increase the drag brake on the MM but thats now my new problem

an time i try to select rock "Crawler Full On" mode in the drop down menu i get this error


" Unhandled exception has occurred in your application. if you click
continue, the application will ignore this error and attempt to continue
if you click quit, the application will close immediately.

Value of -1 is not valid for "value". Value should be between
Minimum and maximum.
Parameter name Value "




before i tried changing it to rock crawler mode my drag brake value was 100

so how can i fix this and get the Crawler mode working, i have herd allot of good thing from people who are using it.
