Power Pivot Broken?
Recently I had an issue where PowerPivot for Excel 2013 just stopped working. I tried all the normal tricks of disabling the addin and re-enabling it. This time it was really broken. I found this link, ran the automatic repair tool for PowerPivot (there is one for Power View too) and all fixed.
Another option to try is first to run Excel in Safe mode (goto run and type “Excel.exe /safe” without the quotes), then turn off all Com Addins, then shut down Excel, restart in normal mode and turn them back on.
