Hi Philip,
Our problem turned out to be our Virus software flagging a critical component of Nitro which is "Nalpeiron Licensing Services". This file loads at startup and tells Nitro that you have a licensed copy of the software during launch. Since our Virus software was flagging it, it would scrutinize this file every time Nitro was launched, slowing the load WAY down. It was very frustrating. We were able to tell our Virus software to ignore the file and voila! It opened swiftly again. Go to your running services (workstation) and you should see Nalpeiron Licensing Services running. Dis
