Cannot see data in a report/workbook

Hello,

When I open a report/workbook I cannot see the data. I can see the Dimensions and Measures, but no data. My coworkers can see the data, but I cannot. I'm new to Tableau so I'm pretty sure it's me , but I cannot figure out what I need to do. Attached is a screenshot of what I am referring to in case I'm using the incorrect terms.

Thanks for your help!
