I have a desktop computer and just got a laptop donated for when I travel. I have a license and have 10.5 on my desktop computer. Now I want to also have the program on my laptop. I don't understand the deactivate information. I want to use the program on both my computers. To further complicate things. The donated laptop is windows 98 and I have xp on the desktop computer. I tried to load the program on the laptop but it would only let me load 10.3. I then downloaded the 10.5 from the web with my license number but then it said something about deactivating and I got lost in what to do. This may not be an issue for this forum but perhaps others have this problem too. Barb
