Hello,
I am really sorry for your bad experience, but I haven´t found any your post or e-mail about your problem with Book it!, so we couldn´t try solving that issue.
Every customer obtains e-mail about license prolongation 2 weeks and 3days before license expiry. If they don´t use discount link, they can´t renew their product license under the same conditions as bofore the expiry. So if your license is expired, there is no any other possibility then make a new purchase.
Maybe you will pleasantly suprised when you try the newest Book it! Also, please, don´t hesitate to contact us, if there will be some issue (in such case, you decide for the purchase of Book it! 2).
