I patiently downloaded and installed PTR, and when that was completed attempted to give it a go. I clicked to load the game and it started just as it always does until it came to a message stating "I had not been online for the last 30 days, and to please start the game while online." An interesting message since it's been less than 24 hours since I was last on. I had to force quit, D2r and restart it and again I received the same message. I switched to D2r, quickly ran the last few minutes of Tamoe and Pit TZ, quit, set it back to PTR, and received the same message again. I then restarted the pc, loaded Battlenet, and once again received the same annoying message. So have fun with PTR!
