Dear calligulus,

Your purchased license is the permission to remove the ads/links to BoonEx. Other than that you are not limited to any particular version of the software which is offered for free download for everyone. Once you install the BoonEx product, all the upgrades are still free for download. We provide detailed upgrade instructions for every new patch or version. Look up here http://www.boonex.com/trac/dolphin/wiki/DolUpgrade. If you require assistance from support, you can order the see more installation service.

Please try to post support questions in the forums as was pointed above.
Thank you for understanding.
