I was fooling around in the Cavern and found the Bahro cloth to Descent at the end of Tokota(sp?) Alley. Clicked on it and got the normal transport sound to a black screen with the GoW Logo. Waited for something to happen for about 5 min and got a pop-up - "UruGehn Error" "Link to Age Failed". Clicked OK and found myself on my desktop.
I re-entered the game and found the City Book on my Relto bookshelf with the link picture to Descent in it. Clicked on the picture and the same sequence of events occurred - black screen for awhile then Age Failed pop-up.
I hope this is just a small glitch (if it really is a glitch) - I was really wanting to get my music player.
All things come to those who wait.
