Marlin Firmware Problem (3 replies)

I am trying to move from Sprinter to Marlin but I am getting an error when I try to connect to Pronterface. The error is:

Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

I followed this tutorial on how to edit the Marlin Configuration.h file, but did not work:

Any idea?
