Hi everybody,
if you're already using eXtroForms lite and have then purchased the commercial version, you should download the correct installation file.
Login to
www.extro-media.de, go to the download area (click Software -> eXtro-media Download in the menu) and click on eXtroForms. Please note that after you've purchased a commercial extension, you'll see an additional category in the download area. Click on the product you've purchased (eg eXtroForms) and download the commercial version.
After downloading, install the extension in your Joomla.
