If you have Urchin installed, do the following steps to buy and add Urchin licenses:

1. Enter your admin control panel.
2. Select Urchin licenses in the INFO menu.
3. In the Get Key Code for logical server section, select a logical server from the list and click Get Key Code to generate a key code.
4. Open a new browser window and go to https://secure.urchin.com/urchin3/buy-dedicated.cgi.
5. When prompted for a key code, enter the key code you have generated. Specify the number of licenses you would like to buy; then proceed with the wizard. In the end, you will be given a pack of licenses.
6. Go back to the Urchin licenses page.
7. In the Add new licenses here section select the same logical server and enter the serial number, license code and the number of licenses you have purchased.
8. You can repeat steps 1 to 7 when you run out of Urchin licenses.

* To check how many Urchin licenses have been taken, please use Urchin license manager in your admin panel, not the Urching config file, because the latter only reads the accounts that produced log files for the previous day and ignores accounts without logs.
