Virusim,

The problem is usually caused by configuring FPW to use a drive other than C: for its temp files during compilation. Make sure that your config.fpw's TMPFILES (and PROGWORK if present) points to a directory on C:. Then check the "Rebuild All" files check box and re-compile. This should solve the problem.
