Problem activating subscription

Last week I paid for an annual membership using the email, with a username oglethorpeuniv. I installed the plugin logged-in to our WP multisite network with my admin email The dashboard plugin installed without a problem, but because the emails don't match, it doesn't recognize my membership. I tried changing the email, but it won't let me. I also tried installing the plug-in logged in with the other email, and can't do that either. Is it possible to change the email for my account (oglethorpeuniv) to so that the already installed dashboard recognizes the paid membership? Thanks!
