Cannot create/shadow copy ?

[Guest]

I keep getting this error message and i don't know whats the problem is and
how to solve it. I have a webproject with 2 components (dll) added to it. One
is called PhotoGallery and one is called Photo. Any suggestions on how to
solve this? i can't do much at the moment.

Server Error in '/PhotoGallery' Application.
