The Fiber Guides don't Work for Me

I normally use the Fiber script 2.03 with Blender 2.34 for grass and weeds. But now I need to use the Fiber Guides for eyebrows.

When I attempt to use the guides I get errors then the script crashes and this reads out in the console-

skip: 40, x: 640 y: 640, depth: 24 (18)
Unable to read parameters.  Please run the GUI first and make sure you have file
 creation permissions.
Traceback (most recent call last):
  File "FiberGUI.py", line 213, in bevent
    ControlPoints (sldControl.val, sldCtrlSeg.val)
  File "Fiber2.py", line 327, in ControlPoints
    LoadPreset()
  File "Fiber2.py", line 60, in LoadPreset
    FVersion = readfloat(f)
UnboundLocalError: local variable 'f' referenced before assignment

Thanks for your helpful tips in advance folks.
