Revisit Extruder Problem

[newman13f]

Hello everyone, previously I've posted about an issue (among other members) with my extruders on my Prusa i3 Pro C not feeding any filament. I still have not been able to solve this problem. Both stepper motors work if I swap the plugs with one of the other axis ports. Also both hot ends heat up to the appropriate temperatures. Both nozzles are free of debris and the filament is able to pass through just fine. I've been told to reinstall Marlin to the GT2560 board and everything should function properly afterword. The problem I'm having now is when I attempt to install Marlin through the Arduino software I get an error that I will copy and paste at the bottom of this post. Has anyone else run into this, or does anyone know how to solve this error? I've tried many different solutions with zero results, just keep getting the same error. Also I'm using a Macbook Pro laptop to run my printer. I was able to use my printer for almost 2 months before the extruder problem presented itself. I appreciate any advice in advance.

Here is the error I've been receiving.

sketch/temperature.cpp: In function 'void manage_heater()':
sketch/temperature.cpp:665:1: error: unable to find a register to spill in class 'POINTER_REGS'

How about use other arduino versions?

I have tried that with the same results.

I've never got those errors. I use arduino1.0.1, and it always works. You can try it again.
