I installed SW on my system about 18 months ago, and everything worked fine,  But then I come to render something in Photoworks, and it is not there, so I went to tools and re-added it.  When I reopened SW it comes up with an error message 'Cannot be loaded. Either the Add-in or one of its components is missing'.

SW still works, but I am unable to render any of my work.

Any suggestions on what I should do???
