If I am understanding correctly, you are trying to upload a list of email addresses into your account, but are getting stopped once you select the file from your computer with an error message that you need to match the columns in order to continue? If this is the case, what you can do is be sure each column has the correct field name assigned to them. Check out this FAQ on how to import a file from your computer. Any column that is hilighted red, needs a field name for it, and there can't be the same field name fore more than 1 column, so be sure each column is different! I hope I was able to assist!
