This was one crazy mess!

First I tried digging around in SharePoint Designer with no luck. In Designer, when I clicked on Lists and Libraries, nothing would appear in the right window. Odd. When I clicked on All Files, all my items would appear. But, if I tried to right click on the masterpage folder I would receive and error. Then… I noticed when I tried to open the Documents library in my site it would say something like the webpage does not exist.

Onto the ULS Log Viewer.
Started up the Viewer, then made SharePoint toss that error again.
Looked in the Viewer and found that SharePoint error-ed out because of the Documents library on the site. No idea why this single library was the issue. I couldn’t open the library, so I tried to attack it with PowerShell.

 $site = new-object Microsoft.SharePoint.SPSite("http://sharepointed.com/")
 $web = $site.rootweb
 $list = $web.Lists["Documents"]
 $list.Delete
 #do a .Dispose()

Ran this code, then went back into SharePoint, and tried to create a new Document Library. Shaaazam, it worked!

It worked but my Documents library was still showing up in the _layouts/viewlsts.aspx view.

Still working on this issue.

*one note.
For some reason, if I tried to access the site from a PC without SilverLight, I was able to create new Libraries.
