Theme update issue

Hello Sakin I'm now being faced weth an issue I seem not to be able to solve by myself. I tried to update my them, adventurous pro, from 3.0 to 3.3, the latest. For that, I firstly installed the plugin, Catch updater of ver 0.3 and now the plugin is active. Then, I tried to update from the adminpage of dashboard. And what I got instead of right updating process is the below message. "An error occurred while updating Adventurous Pro: Update package not available." I thought the catch updater plugin would do the job. What am I missing? Please let me find out what's wrong with it. Thank you.
