I am trying to import Product and Customer data into my new Magento install (CE 1.9.1) I have the CSV files correctly formatted based on the export files but when I upload and click on check data I get the error "uploaded file has no extension".
What does this mean and how do I fix it?

The message is intended to mean that the filename of the file you are importing doesn't have a file extension. That is to say the file you are selecting to import is called something like
customersrather thancustomers.csv. It attempts to validate the file extension as this determines what type of adapter to load (csv, xml, etc.).
