.dll issues, please see if you can help.

I am currently working on a .NET Web Forums, i Have 2 .dlls that are in exact connection with the main code.
(embarque.dll) and (doca.dll)
After fixing some bugs and altering a couple of things on embarque, it seems that the program wont run anymore.

I keep getting the fallowing error, which states that the error seems to be on my Embarque.DLL but that it is also related to the doca.DLL.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileNotFoundException: ?

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Administrativo.PFA.Doca' could not be loaded.

=== Pre-bind state information ===

Im not really sure of where to go from here.

All suggestions are welcome.

P.S: Both .dlls are pointed by the Web Forum and one of the .dlls (embarque) points to the (doca) .dll

Ive tried to do all that comes to mind to this code and still cant get it too work.
Let me nkow,thx.
