Hi,
Have you updated your IDE and it now won't compile?
OR
Have you had code compile on this version IDE successfully before?

You may have to re-install the IDE, as it seems to not be able to find a file.

Hi Tom, thanks for the reply.

I have not updated the IDE, i have used this version for some time, with no issues. I have re-installed the IDE but it will not compile anything, even a new project will not compile.

regards
