It is possible that some fuctions that we used during the creating of the project are renamed in newer AVR Studio and compiler versions. For example, it seems that function CALIB was renamed to CAL in later compiler versions. Make sure to change CALIB –> CAL.

Furthermore, it seems that the latest WinAVR compilation features a bug in one of its main components that prevents it from proper starting in newer x64 bit operating  systems. You would need to replace msys-1.0.dll (located by default in C:\WinAVR-20100110\utils\bin) with a modified one that might be downloaded from here: http://www.madwizard.org/download/electronics/msys-1.0-vista64.zip
