SalesCart lnk not available

I've always worked in C:\ mode

Under certain conditions (Such as when Web is populated with product) I do not have SalesCart Lnk available as a selection option. This seems to ONLY occur if I use a populated web. When I create a bare web & add salescart SQL to it I have the option available. When I create a Salescart SQL web & add a bare web to it I have the option available. I only have the problem when I try adding a salescart SQL to a web I've finished & am ready to publish after adding Savescart to it. At this time when I choose to add a product lnk to an opened product web page, the popup opens & I only have the option to add the Visual Nav Bar from FP2000 (NO Salescart SQL product lnk choice is present).
