Well there's your problem. The ASI ZWO camera is a high frame rate video camera which PHD just can't keep up with. I had exactly the same probem and tore my hair out trying to get it to work, a few have but for me it was much easier to simply use Metaguide - which is designed for high rate video, doesn't lock up, and supports the ASI cameras in native model. Metaguide is free, try it, it should work right away. Just enter your ASI details in the Setup page. Good luck.
Before the rants start from PHD devotees, i should add that there are ways to get PHD2 to work with the ASI cameras Now but it requires fiddling around with a number of factors in setup. At the time I began PHD2 did not work at all with ASIs. Never the less, Metaguide is still so essy by comparison that imho all beginners shoud start with Metaguide.
