No brakes or reverse on MM running brushed

[E-Revonut]

OK, got a SC10 last week and after two packs the stock esc went up in smoke after I pulled it from the track. I'm thinking, no big deal I have a MM I can put in the truck. Today I get it all set up, had to go to the lhs and have them update the esc so I can use my field card ( please make a Mac compatible Castle Link program). Came home hooked it up and went to use it. Goes great forward, seems a touch faster than the stock esc, still using the stock Reedy Radon 17T motor. However when I hit the brakes I get nothing and when I tru using reverse I get nothing. Any Ideas? Esc worked fine in my CRT.5 with a Medusa brushless motor
