First of all, your new release really works fine.
But I still found an Error on my Site. I have an Site Collection working only with FBA and extended this to an new Port with NTML Authentication. When I add the Web Parts from your Solution to my Site and open it with the FBA Site everything works perfect, but when I open the Site with the Windows Auth Port I get the follwoing Error:
An unexpected error has occurred.
Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator.
