Howdy - just installed the demo and on launching it I am getting a 523 error. The first time I launched, I passed the initial "you have started the trial" screen and was then greeted with a BSOD. I was not able to catch the module that was the root of the BSOD. Every subsequent attempt to launch after restarting has resulted in an immediate 523 after the splash screen displays.
PC: Intel Core2Duo/4GB Ram/Win7 x64
Audio: have tried both with default onboard Realtek audio and EMU 1616m.
Happy to provide any additional information that may help.
