Refresh error: The type initializer for Microsoft.Mashup.Engine1.Library....threw an exception

[Anonymous]

I am brand new to PowerBI so this is probably a simple fix. I'm trying to refresh a Power BI repor that someone else created. When I click refresh on the report I get this error: 

The type initializer for

Microsoft.Mashup.Engine1.Library.SapBusinessWarehouse.SapBwMicrosoftProviderFactoryService

threw an exception

I get a number of errors after this but I beleive the rest of the errors flow from this one.

What can I do to troubleshoot this error?
