The current version of Curviloft works just fine. An earlier version won't fix your problem. You don't have a unique version of SketchUp and the current version of the plugin works for thousands of users.
Try this. Rename the Plugins folder to something like Plugins Original. Make a new Plugins folder (make sure you have full admin priveleges and install the Curviloft and LibFredo files in it. See if that works.
Well it finally worked, huge thankyou to Dave R and TIG for taking time to help me out on this.
