PC > Mac compiling error

Hi Guys,

recently moved on to mac from a PC version of Arduino - used to compile fine on win xp. Now using the latest mac arduino i get this error:

Any thoughts/help appreciated =(

There's no reason for the error. Try downloading the package again and/or moving the Arduino app icon to a different directory.

Thanks for the reply James, I tried this and it still kicked out an error... is there an optimum place to put it?

FYI i'm running the latest version of Lion.
