mapping with an APC40 Knob not working properly


One of the knobs in the devices controls section is not working properly, everything else works fine. The knob will work sometimes but after some time it wont control the parameters, though it lights up and the leds light accordingly to the movement of the knob, but:
1) the leds wont get "filled" when turning the knob up, it will just mark with a single led the position.
2) after i close ableton the leds on that knob stay lit.
What is wrong? i´ve checked my mappings and midi assignments and its nothing there, i use the default mappings or map to macros (in this case it can't be done with that knob, it just becomes useless when it wants to)
the apc40 hasn't even been with me for 2 months, it's a brand new product, not used before, i'm using all the original cables and it hasn't been moved from my desk since it came here. 
Help, please!

    look in your midi selection on right on the top if you have some midi saves there delete it and it should work
