bayscribe

I currently work online using Bayscribe Version 3.0.477, Microsoft Windows XP version 2002 service pack 3. I am considering purchasing Instant Text Pro tomorrow and need to know if it will work or not. Dont want to put that much money out for something that wont work and if I can avoid the hassel of ordering it and it not working I would like to do that, and purchase a different program that is compatible. If it is compatible is there something I need to do in order for it to work with bayscribe, I have read where there are different settings you have to do and disable. Any help or information would be greatly appreciated!!
