Could not load file or assembly 'Nop.HttpModules.MembershipModule'

Hi, I'm trying to access the "Administration area" of the site and always get this message, the site of the store works, but the "Administration" appears the following message

[quote]Configuration Error

The assembly 'Nop.HttpModules.MembershipModule' is contained within the folder / bin and all the others.
What to do? :(

Thanks

Anyone?
I noticed one thing, I created a directory "/ bin" directory within the "Administration" and stopped the errors, but mistakes happen from redirects.
Apparently he sees the the "Administration" as a new application
