You can findout which Unirgy Modules you have installed by logging in Magento admin area and go to System > Tools > Unirgy Installer. Then click on Manage Modules tab.

Installed column will show you the version of the module in that row. If background colorr for that cell is Red then module has an update available. If color is Green then module has latest version and if color is Orange the version installed is not recognized (it happens when you have customized version installed.)
