I was given a free download of CS6 Design Standard from my work, which I have used. Then, last week, I was uninstalling the trial version of the CS6 Master Suite (which I had also been using and had expired), but in doing so, I accidentally uninstalled the design standard. Now, when I go to re-install it with the same serial number I used before, Adobe says my serial number is invalid. How can this be? And how can I get my programs back? Please help!
EDIT: Turns out I was using the Mac serial instead of the Windows. Glad it was a quick fix!
