Error When Trying to Connect

Trying to get data from a SQL database that has the On Premise Gateway installed from PowerBI Desktop and getting the following error:

Details: "An error happened while reading data from the provider: 'System.IO.FileLoadException'"

Here is the Mashup Container log, as I've read can be of help, although it's not assisting me at all.
