That seems to be an issue with Joomla loading the update information from our server when it automatically checks for updates. I'm not sure why that's happening in your RocketTheme template at all.
I'd recommend trying to go to the Extension manager -> Updates area. Hit "Refresh" and see if that helps the situation. If not, let us know.
We've found the issue. In our XML setup file, there's a space around the update server address, which is causing Joomla issue. It's easy to fix on our end by re-packaging the files, and we will release an update over the next few days with this and some other minor changes.
We just posted Beta3. The main change was simply an update to the update server which should hopefully fix this silly issue.
To install, please do the following:
* Uninstall beta2 from the Extensions Manager area. If you don't do this, Joomla won't change the update server, for some reason
* Install beta3 like it's new.
All your configuration settings will stay, so you shouldn't loose any data or anything when you uninstall.
