For various reasons the VirtueMart forum cannot provide support for third party/Commercial joomla/VirtueMart templates and themes, modules, plugins, template overrides, Artisteer templates etc.
Unless we use an exact copy of that template or addon we do not know the code or what code changes or overrides the developer made to standard VM function and layout, so support for these should be sought from the third party developer, either though their forum, ticket system or by email. This includes addons released under GNU General Public License and similar where the developer uses a membership support service to cover their development costs.
Where the developer has a message thread in the 3rd party extension board you can ask there. http://forum.virtuemart.net/index.php?board=135.0
Where possible the forum volunteer staff will suggest where support for such products may be obtained.
Note that if you post commercial theme code in the forum you may be in breach of the developer's copyright restrictions.
