There is a very good reason that you are probably having this trouble. I had
the same problem with my Vizawrite program the first time I loaded it. It
turns out that Progressive Peripherals & Software (the maker of Vizawrite)
produced the first of the saleable copies of the software on a prototype Amiga
2000. Certain bugs in that system caused problems in all the copies. Another
symptom I got was that the program would easily lock up after I finally got
that version to load.
Just call them at (303)825-4144 (Colorado) and they'll send you another copy
(Version 1.02). Tell me how you like it when you get it running.
