ZD 7.0.1 was working fine until that upgrade to 7.1.1 came about. Now ZD is no longer working. When I run the ZD 7.1.1, the DOS window shows up very briefly then nothing happens. And I had to reformat my PC to be able to upgrade from ZD 1.0 to 7.0. Now this!
BTW, my OS is Vista Business running on a 4GB RAM and Quad CPU (Q9400).
