If you downloaded the shareware version of PocketMetro, you will be able to start the application 5 times. In order to lift this restriction, you have to purchase a registration code. Registration codes are available through several resellers, including Handango or directly from ClockLabs.

In order to unlock your version of PocketMetro, you must select the "Register" option of the main screen's menu (this option is missing if your version is already registered). The Registration screen will pop up:

The registration code must written in the "Code" text field. Then you must select the "Register" option of the menu. If the registration code is correct, the application will be unlocked and a confirmation message will pop up. Dismissing this message will redirect you to the main screen of the application. If the registration code is incorrect, an error message will pop up. Dismissing this message will redirect you to the Registration screen where you will be able to modify the registration code and submit it again.

When the application has been started 5 times without being registered, the Registration screen will come up immediately and you will not be able to use the application without entering a registration code. The About screen (available through the "About" option of the main screen's menu) shows the number of remaining starts.

A registration code is only valid for one city and one version of PocketMetro. For example, a registration code for PocketMetro 2.1 London will not work for PocketMetro 2.1 New York. Similarly, a registration code for PocketMetro 2.0 will not work for PocketMetro 2.1. So, if the registration keeps failing, please check that your registration code was really intended for your version of PocketMetro.

Registered users can obtain a new code for an updated version of the PocketMetro for free. Simply write to support@clocklabs.com with your full name and we will send you a new code if we can find your name and email address in our database.
