Reference Not Being Recognized - Visual Studio .NET 2003

I am working on a project in Visual Studio .NET 2003 - within this project I have made reference to a DLL, however, when I attempt to access create an object of this type I recieve errors (either Type not found or more recently a method not found error).

I have attempted things such as rebuilding the project, readding the references, and re-registering the DLL via regsvr and regasm, but so far I've been shooting blanks. Also worth noting is that when I view the Modules window under Debug mode, the DLL in question is marked as symbols not loaded.

It's a shot in the dark, but if anyone might have some suggestions on solving this issue, I'd be happy to hear them.

Updated w. error msgs:

COM object with CLSID {277975FD-EDFE-4BC8-8BF0-394DB3C8CC5C} is either not valid or not registered.

Was what was originally thrown - I couldnt find a reference to a DLL w. this CLSID in my regedit.

Another Programmer tinkered with it, and now this error message 开发者_Python百科is whats given:

Method not found: Int32 CmsIntDataLib._InterfaceLog.InsertInterfaceLog(System.String, CmsIntDataLib.JOB_TYPE_CODE, CmsIntDataLib.JOB_STATUS_CODE, System.String, System.String, System.String)

The method does exist in the referenced DLL, name is the same and all the parameters are accurate.
