errors when attempting to activate the plugin

Hi Support Team

I have installed the ithemes security plugin in my site and upon activation we receive the following error(s):

Cannot run iThemes Security. Error encountered during setup. Please try deactivating and reactivating iThemes Security. Contact support if the error persists.

A plugin deactivation/reactivation nor a complete plugin reinstall solved the problem. One important note is that we use ProjectNami WordPress. Are there any post-activation setup steps needed when using ProjectNami?

Please advise

Thanks!
