Import Error

Please help. I'm trying to import data into a form but it keeps giving me an error saying, Error Occurred. We are sorry for the inconvenience. Please try again after some time or refresh the page and try again.

I've made sure that the label names in the view and in the xls file I am importing from match. I've unhidden all fields that I had to make sure it wasn't any of those giving me an issue.

I'm hoping to finish this application by Friday but without the import capability, it is practically impossible for me to test it.

I'd appreciate any more information about this.
