Reply to VC-100 not even sending out MIDI Data for certain buttons?

To begin with, here are the specs
Firmware 1.2 or 1.2 (OLD! I know, but I don't own a windows and havent really ever felt a need to upgrade)
Using Traktor Pro (old again, but not seeing a terribly desperate reason to upgrade yet)
VCI-100 with Traktor Pro Mapping 2 and the matching overlay.

OK so the issue is not with Traktor, not with the firmware (I dont believe it is?), its just when a press certain buttons on the VCI-100 (on the left hand side, there is the SHIFT button to exit the browse mode,and the right hand cue button, and the button to change with FX bank you are controlling) sometimes just dont even send out signals. I know this because there is a little tiny red light that has the label "data" on my overlay. When I press these buttons, this buttong DOES NOT light up, implying no data is being sent out?

Has this happened to anyone else? Ive had the controller for maybe almost 2 years? And have NEVER put it to ANY abuse that may have caused those problems.

I dont believe this is a firmware problem?

Oh, and to make things more complicated, sometimes the buttons do work for 5 minutes or so, then sometimes they dont work at all.

Thanks in advance for the help!
