If you like Jomres and want to continue using it, you can purchase a full license key from us at Jomres.net. Once you have a new key, enter it into the Support key field in Site Configuration then reinstall any plugins that are marked as encoded.
A full license key allows you to download all Core plugins at no extra cost. They will be provided fully Open Source, and once your full license has expired you will be able to continue using any plugins you have downloaded. Alternatively, if you no longer wish to use the trial versions of the plugins then please visit the Jomres Plugin Manager and uninstall any plugins which are marked as encoded.
