Audacity installation fails

For the last few days I've gotten this error when installing Audacity Portable via the "Get More Apps" menu option:

"The downloaded copy of Audacity is not valid and can not be installed. This could be due to an incomplete download or other network issue. Please try running the updater again when complete."

Is there an issue with the app? If not, is there a workaround that I can use to get Audacity working again?
