Data source error2 arguments were passed to a function which expects 1

Data source error:  2 arguments were passed to a function which expects 1

I have set up my personal gateway, and it seems to be running. When I try and refresh my dataset, I get the above error. I am at wits end, but cannot figure out what the issue is. I am on a VM Ware machine, and don't know if this could be causin issue.

Any help or insight would be greatly appreciated!!

Thanks
