The thread title says it all: I have PS7 that I bought from Academic Superstore when I was in college. I skipped CS1, but now want to upgrade to CS2. Will I be able to use the $150 upgrade version, or do I have to pay full price? The reason I ask is because I'm going to download the upgrade from the Adobe store, and I don't want to fork over that money just to find it won't work. I can't seem to find an answer on Adobe's site. Thanks!
