Judging from your signin name (ihatecomputers), I would guess that PCStitch Standard (version 7) would be what you would want. The Pro software has more features, but the 7 is somewhat easier to use.
The importing functionality is not a whole lot different between the two versions. Most of the features and enhancements in Pro are in the drawing and interface area.
I would also like to know if pcstitch will work for me. I want to chart my design that has some cross stitch, doves eyes, and kloster blocks. Will pc stitch pro work for me?
