Repair an ASP.NET Project

I have an ASP.NET project that is no longer supported by the creator. I am told all of the source is in tact but when i open the project in Visual Studio i get many missing references and some errors. I'm sure it's a rather simple fix but i'm just frustrated trying to figure how to get passed this problem and i need a little help. Here are a couple of errors that make up the bulk of the problem. C:\Skillmatics_One\Web\Facade\[login to view URL](40): The type or namespace name 'Category' could not be found (are you missing a using directive or an assembly reference?) C:\Skillmatics_One\Web\Facade\[login to view URL](166): The type or namespace name 'GetQuestionOptionsEnum' could not be found (are you missing a using directive or an assembly reference?) I can supply the project files and some emails between the original creator and myself to the selected coder. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
