Error compiling: 'TCNT4' was not declared in this scope

No matter which provided example I try to upload, I get this compilation error:
C:\Program Files\SparkiDuino\hardware\arduino\cores\arduino\Sparki.cpp:748: error: ‘TCNT4’ was not declared in this scope

Installed Arduino 1.0.5 on Windows 7 (32 bit) Home Premium Service Pack 1, Intel.

Any suggestions?

Make sure you have ArcBotics Sparki selected under Tools -> Board.

Not an expert, just got mine yesterday, but that was my experience.

Thanks, that did the trick!
