I have Adobe 4.0 which I then upgraded to Adobe 5.0. The operative word here is upgraded. Since I have gone to Microsoft XP as an operating system I then down loaded a patch to make Adobe 5.0 work with XP. My Adobe still does not work. I believe the down load patch only works with a full version of Adobe 5.0. I believe since I upgraded to Adobe %.0 the patch does not work and to make Adobe work I need to buy the full version of Adobe 5.0. Can you confirm that before I buy another copy of Adobe 5.0?
