Might have messed up my specialized command post, any help?

So I just got my bike back together from having it shipped out to me, when I got the specialized command seat post back together I noticed it wasn't extending. The cable is attached and the seat mechanism is working, I deflated and then inflated the pressure value in the post but I may have accidentally gone over 50 psi (which is says NOT to do in the video instructions) since I just got a new shock pump from RS that is alittle weird. Anything I can do it get it working again?
