Hi,
1. Only if you have specified Default.aspx as the default document
2. Are you sure your site is not configured for ASP.NET 1.1? It needs to be configured for 2.0
3. When I visit http://www.electcraigriley.com/Setup/Default.aspx I see that you do not have folder permissions correctly configured therefore it cannot write to the log.
4. See Medium Trust documentation
5. I would disable trace until other issues are resolved as trace can have some conflicts and cause problems with some components
Hope it helps,
Joe
