following this tutorial (http://blogs.technet.com/b/mahesm/archive/2010/04/07/configure-forms-based-authentication-fba-with-sharepoint-2010.aspx) I configured the claims for my web app... but something is wrong because i get a error page whenever i click a document in a library (liek to view or edit it)... here is the error screenshot Error SP

everything else is working just ok... this "feature" (people open files and alter without having to download and reupload later) is very critical for my project...
