PayPal had some updates (http://developer.paypal-portal.com/t5/blogs/blogarticlepage/blog-id/mtsupdates/article-id/465) which went beyond the schduled timeframe and IPNs were not validating for that period. PayPal will most likely resend the IPNs and sales will be processed then.

PayPal should now be caught up with any backlogged IPNs resulting from their recent issue; if you are still seeing payments logged with Completed status in your PayPal account history which are not in your E-junkie Transaction Log, see this page for troubleshooting tips:
