Obtaining Your License Key
Your wbTeamPro license key can be found from the Holodyn Client area under the "My Services" section. Visit http://billing.holodyn.com/ and login to the account you created when purchasing your wbTeamPro demo. Click on the "My Services" button on the top menu bar and you will see a list of your available services. Find and open the service labeled "wbTeamPro Project Management for WHMCS". Copy the License Key value to be applied to your installation.
Re-Issuing Your License Key
You may need to Re-Issue your license key if you have moved your installation of wbTeamPro to a new folder or have changed the IP address for your WHMCS website installation.
To re-issue your license key, navigate to the License Details page by following the instructions for Obtaining Your License Key. From the License Details page you will find a "Re-Issue License" button toward the bottom of the license details. Once you have re-issued your license you will need to follow the instructions for "Installing Your License Key" to apply the new license key to your wbTeamPro installation.
Installing Your License Key
The following instructions are for v1.0.0 through v1.7.6.
If you are installing v2.0.0 or higher, the License Key 
is installed from the WHMCS Administration Area.
To install your license key you will need to open the config.php file located in your wbTeamPro installation folder:
/{whmcs}/admin/AddOns/_wbteampro_/config.php
Edit the line that reads 'license_key' found toward the top of the file. Replace the example key with your unique license key.
22: // ***********************************************************************
23: // License Key (example: wbtp-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
24: // ***********************************************************************
25: 'license_key' => 'wbtp-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
Once you have modified and saved the file, the wbTeamPro software will connect with our remote server and validate your installation. You may need to Re-Issue your license if you have moved wbTeamPro to another folder or to a server with another IP address. If you have problems installing your license key, please Submit a Ticket so that we can help.
