If you go to Settings->MIDI Settings->Configure MIDI Connections, which MIDI library do you have selected? It may be worth trying Google if you are on default, or default if you are on Google to see if one works for receiving if the other does not. Also verify that MobileSheets is receiving on the channel that you are using to send on the keyboard.

Thanks alot Mike! 
I switched MIDI library to Google (it was in Default), and MSP found the keyboard instantly, and now everything works perfectly.
