Source Code Licence Setup

I have copied over the source code files into the FileVista directory and kept the App_Data subfolder intact as instructed via email from Cem to install over the trial version of FV but when I try to access the site now I get the following;

Server Error in '/FileVista' Application.

Please advise

As it's the source code package, you have to build the solution so that the DLLs are created in the bin folder.
