can't see power BI datasets using power pivot in excel

[bdv99]

Note the images below, on the left is my screen, on the right the screen of a colleague. Notice the company name is *not* showing in mine. It was yesterday, something has happened today and I can no longer see any datasets.

If I open a workbook from a colleague, then I can refresh data. I can also see the datasets in power BI web. I can also see them in Power BI desktop so I know it's not a permission issue. Something specific to excel.

Any ideas ?
