I ended up doing a reinstall after my post in the previous thread. Again it seemed to download and patch smoothly. I get the cryptic loading screen, then the Neverwinter loading screen and then just a black screen with the NW version number at the top at which point my computer freezes entirely, even the time display! I've tried choosing both low graphics settings and default settings when prompted on log in but the result is the same either way. I've tried leaving it to see if it comes good but it stays stuck for hours.
I'm using the latest version of both crossover and the crosstie, but I have a MacBookPro5,5, nvidia GeForce 9400M, osx 10.6.8
I'd be grateful for any suggestions...
