Thank your for downloading and testing JQuarks and we apologize for the encountered issue.
You probably haven't unzipped the downloaded file. Since JQuarks includes a component, 2 plugins and a module, you have to unzip the downloaded. Then you need to install each of them and publish the 2 plugins and the module. This should immediately resolve your issue.
These two links would probably be in help:
1. JQuarks installation guide: http://www.iptechinside.com/labs/wiki/jquarks/Installation_Guide
2. Similar question raised by a JQuarks user: http://www.iptechinside.com/labs/boards/5/topics/show/361
Hope it helps and make you review your rating :)
