Thank you. I reinstalled Extension Store and problem corrected.

Yes. I've tried those suggestions without success.

I have purchased Fredo6 Curviloft and successfully loaded on my desktop. I have installed on my laptop but it is unresponsive to selection via icons or menu. Tried uninstall/reload validate license. Get the following error message.

Error; #<NoMethodError; undefined method `visual_version' for SCFLicense;Module>

Any suggestions?

Yes both files are present.

I have downloaed bezierspline into Sketchup 7 (Plugins file) on a Windows XP home platform. I have been unable to access the ruby. It doesn't appear in DRAW or PREFERENCES-EXTENSION. I believe I have followed the instructions and have successfully downloaded other Ruby's. Has anyone else had a problem or can make a suggestion to implement this.
