I tried everything I could think of, I sent to SMS tech support and went round and round with them. I kept getting the pop up telling me I need to activate the program even though I it had been activated and working properly prior to the installation of the SR. When you launch P11, is it that it does not launch at all or do receive a warning box telling you that you need to activate the program? After I installed SR3, I tried to launch P11. You can easily fix the problem with P8 simply by going into your windows upgrades list and uninstalling the upgrade to IE 11. Did you let Windows upgrade IE from 10 to 11 around the time P8's library stopped working? SMS issued a SR to correct the problem caused by the upgrade for IE 10 to IE 11 but the fix only covered P9 and up.
