It works absolutely brilliantly for me. Explain more and someone may be able to help you. Tell us exactly what you have done and what you are trying to do.
I go yo Picasa, select the photos, click the TribalPages button, enter login and password,select folder in Tribal pages. It then processes the photos. The last step tries to access Tribal Pages through the browser (Explorer) and says it cannot find TribalPages.
