invalid serial number

[ddorsey12]

I recently received a new computer and cannot find my cd to install my acrobat professional 9.0 license.  When I try to install Acrobat Pro 9.0 with my serial number I receive a message saying the serial # is invalid.  I contacted customer support and they told me it was a technical issue I would have to go to the forums for help. Please advise.

Are you using a computer Administrator account with full read/write permission?
