Post title: Error message using DGT memory

I have added the DGT memory file but when it comes to using it I get the following error message:
could not load file or assembly Oracle. DataAccess The assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded
Does anyone know what this means and how to fix it? Thanks
