I just installed Adobe CS3 (what an ordeal that was!) and activated online to make Adobe Acrobat 8 work. You'd think that was done for Adobe... no!
If you have Adobe After Effects 7 (to make matters worse I have AE 8 Beta) installed, you need to re-activate the already activated After Effects, because there's a new activation code.
Now if like me, you tend to travel to more remote places with no or limited internet, this can be a PITA. Luckily I just checked before I left. Just to warn follow Adobe users of this new protocol.
