I am having this same issue using the actual product and not the demo CD. I have tried two different systems, same problem-- everything goes flawless until I try to create vg0, when I click 'add', the screen refreshes and it still says 'new'. I have even tried moving the drives from the RAID controller to the standard 2nd IDE port on the motherboard, etc. with the same results. I just can't seem to get vg0 created.... bah. Any help would be appreciated.

Setup (old lab box):
-PIII-1000 CPU
-Tyan S2515 Tiger LE
-1.5GB RAM
-(2) ATA100 Hard drives
-(1) Intel GigE NIC

Everything goes fine until trying to add vg0 so I can create some targets. Let me know what other info I can provide to try and assist. Thank you.
