The packages are offered for free, all styles and language packs are original, we also didn't test it, and you use it at your own risk. Please don't consider that the issue is our fault/mistake. Uploading styles and language packs in the packages may overwrite your existing styles and language packs. You are advised to backup your all styles and language packs and update your files manually if you get duplication. You may need to re-install MODS on styles and language packs.
If you have any questions/problems, please do not hesitate to contact us at our helpdesk (http://www.echophp.com/help/) at anytime.
