Are you trying to import them from a 3rd Party (i.e. AOL, Gmail, Hotmail, or Yahoo) or are you trying to use a spreadsheet? Let me know and hopefully I can help.
Like Michael suggested, contacting IDEA would definitely take care of this if you had the time to give them a call. You can also “Live Chat” with one of their representatives when they’re available online. Just look for the “Live Chat” link in the upper right hand corner on any page of IDEA’s website.
Best of luck to you solving this problem soon!
