Typically, our policy is to provide updates to all customers for minor releases. For example, if you purchased a module that was version 01.00.00 you would receive all updates within the 01.xx.xx version. In order to download a new major version release you would need to subscribe to the site. A subscription to this site provides access to download all versions of all our products as long as your subscription is active. The other option would be to purchase the new version of the module only.
Since, we stated that the version 1.x version of this module only allowed for one instance per page, and designed the first version of the module to be used that way, the ability to add multiple buttons to a page is not considered a bug. Therefor we did not include that feature as a patch to the 01.xx.xx module. We consider the ability to add multiple buttons a feature that was added to the 02.xx.xx version of the module.
With that said, please contact us via email at support@itlackey.net and we may be able to arrange a different solution for you.
