Acquisition Pop Message Repeatedly Pops Up

Hello – I recently downloaded the NextGEN Gallery and am trying to use the it but the blue “Important Message” regarding the acquisition of NextGEN by Photocrati repeatedly pops up a few seconds after each time I DISMISS it. I have clicked on all of the links and it continues to popup. Please tell me how to make the pop up message permanently disappear so it will stop blocking my screen. Thank-you
