I did not try that.
However, I just spoke with tech support and they said my serial number doesn't even show up in their database. I purchased my old laptop with the CS5 master suite as a package deal from a friend in college 5 years ago. I have no way of contacting him today. I am now afraid that if I deactivate my key from my old laptop that I will no longer have the working programs, which are critical to my work.
