Excel 2013 - PowerPivot Data Model Source Issue

[sstyre]

Hi all, I've been recently having some issues with trying to create a data model in PowerPivot that pulls from an excel file. I can connect to the web, SQL and more just fine, but whenever I try to connect to any excel sheet, I get the following error. Does anyone know how I can rectify this? I'm running Excel 2013, 64bit.

Thanks in advance!
