PKGi Unresponsive

I recently installed PKGi by following this guide: https://www.reddit.com/r/ps3piracy/comments/myu7ft/how_to_setup_pkgi_and_get_your_own_freestore_to/, however, I cannot press the Triangle button to open the menu and refresh the application. I cannot use any buttons on PKGi, but I can use the PS button to open the XMB menu, and everything works there. How come PKGi is not responding to my controller inputs?
