assembly and strong name help

Question

Hi,

I have a project which is jst a plain .dll, and this project all has a reference to another third party .dll file which is also based on vb2005.
So when i try to register the project .dll it says i need a strong name; so i gave it a strong thru Project>Properties>Signing>sign The assembly.
now when i try to compile, it says my other third party .dll does not have a strong name, so i assign a strong name to it to. but now i add the reference to the new third party dll with a strong name .. it does not recognize one of its member classes or maybe the whole assembly ... i cant seem to understand whats going on, i have tried everything i can but after i add a strong name it gives me this error... Here is the error it gives after i assign strong name to the third party dll

Reference required to assembly '' containing the type ''. Add one to your project.
