Create a branches.key file by clicking the Key Gen button in the about dialogue in the branches modify panel. Email your Branches.key file to info@v-tree.net using the same email address as the one used to make payment. Once payment confirmation has been received you will be issued with a license file within 24 hrs. Place this file in the same directory as the branches.dlo plugin and restart 3dsMax. The license is $70 USD and is usable only on the pc with the hardware configuration used to create the key file.
