Problems with camera

I am experiencing some problems with some of the vvvv modules: Camera+AxisAndGrid. It seems that they cannot be detected. It happens to all the patches that have these modules, any idea?
herewith a snapshot of the help file
thank you

here it works.

maybe you modified something in the folder structure of your modules, e.g. renamed a subfolder?

move cursor over the missing node and wait for the tooltip.
it will till you something like
this is the folder where vvvv expects to find the missing modules.

read about paths

Hello Kalle:
you were right, it had to do with the path of the modulo.
Thank you!
