I need to deactivate one of my adobe CS5 licenses on a computer that has died. Adobe's troubleshooting leads down the path of contacting customer support but this is not possible through Adobe's website troubleshooting since that only leads you to using forums as a solution. Any suggestions?
You need to contact Customer Support thru chat and ONLY ask them to reset your activations. Any other request is likely to lead them to turn you back to the forums.
For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...
