I've started getting this error on several of my datasets in the service:

An error occurred while processing the data in the dataset.Hide details

Is anyone familiar with this? I REALLY need to get this resolved - several of our companies are starting to adopt Power BI but not being able to refresh will be an issue. I can refresh from the desktop and publish to the service just fine. It just doesn't work to refresh from the service.
