A common error when users try to import tokens is an invalid CSV file. This is often caused by Microsoft Excel. Many users have a list of email addresses saved as an XLS document. A file can be saved as CSV in Excel, however, depending on the locale of the OS, Microsoft Excel may use semi-colons as comma separator, while a standard CSV file uses commas  as separators. If you do not know which one you use, open the file with a standard text editor and check what separator was used.
