I'm using a package who's set as free and when I go to My listings and click on the Renew/Upgrade Package option on any listing then clicking Next I get this error:
Logic error occurred, contact Flynax support please...

What's this and how can I fix it?
Btw, I noticed that one listing is missing and when you open the link it gives only the Price History box
