VB.net Error - Reference required to assembly...

So yesterday, I was having some kind of permissions issue with my project that would cause any page I edit to bring up a login dialog that I was unable to do anything with. Right clicking on the file in windows explorer and adding "Everyone" w/ full access to the file solved the problem. However, since it was any file I edited, I went in to the advanced menu and check the box that makes that setting recursive. That made that issue go away, but made a new one appear. Now on any file I edit, I get a compiler error -

Compiler Error Message: BC30652: Reference required to assembly 'App_Code.ckfld69-, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' containing the type 'cDataAccess'. Add one to your project.

Source Error:
Line 86:
Line 87:                   With Master
Line 88:                         _DataAccess = .DataAccess
Line 89:                         .MenuId = 0
Line 90:                         .ParentMenuId = 0

As you can see with the attached image, going to the definition of dataaccess seems to find it fine. Do I have to reset my references somehow or can anyone tell me whats going on??
