Got a surprise this afternoon when I went online and engaged Powershadow for the first time in a couple of days. Clicked on it, hit start and nothing happened. Then a box opened that said my trial period had expired. This is v2.6. I checked everything and it still showed it to be a registered copy, same one I installed way back when I found it. Everything checked out, but tried twice more to open it and same box telling me the trial period had expired. Uninstalled and reinstalled my copy with the serial #, but no luck, same warning and it isn't functioning. It was nice while it lasted.
