Error when creating a new route

In the last fortnight or so, I've been getting this error message when using the 'Direct route setup' in RW tools from the route building tools menu.
Error #53 File not found
Module: frmRoute
Procedure: Command4_Click
I think it may have something to do with the C:\program files folder being read only, but I'm not sure how to change this. It's only been acting up in the last fortnight or so. Is there a way to fix this?
