Hello, if you are using magento 188.8.131.52, you must use the theme in the Magento 184.108.40.206 folder. Be sure to install it in a clean magento install, because if you had customized the theme or setted up an extension before updating, it may cause conflicts.-
Hi again, our themes are compatible with 220.127.116.11 so far, the theme will not work correclty if it´s used in 1.5
We are waiting until version 18.104.22.168 gets improved, so we can upgrade the themes.
Also, please don´t use HelloUpload extension, this extension is under re-configurations tasks, and we will let you know when it´s available.
You can set up the theme manually: http://www.hellothemes.com/uncategorized/how-to-install-theme
