CTC 3D Pro Heater Tempeture Read Failure!

Hello all. I'm having an issue with my CTC 3D Pro. First I started getting this message: . It also said my right extruder was heating up at times, and it wasn't even hooked up. I unplugged the Thermocouple wire for that extruder, and although the message still showed up about a temp problem when starting, it would let me print again, for a few weeks now.

Come yesterday, the other extruder now says N/A for my temps: and I am unable to print. If I unplug, and plug back in the connection, it will show the temperature on that extruder start working and heating up, for a second, before going back to NA. 

Anybody that could be of some assistance? I had e-mailed the company about the original problem and they had basically just said maybe thermocoupler. If the wire needs replaced, where can I get this type of exact wire at? I'm getting better at working on the actual hardware of things, but I'm no pro yet and not that great at finding specific wires for specific things of this nature. Thanks!
