I lost a software key for Camtasia -- which I purchased through the App Store. No way to recover it.
I bought Camtasia 3. When trying to update through the TechSmith site, I chose "Replace" old version, not realizing I'd need the software key -- which I now cannot find. Anyone else had this problem and solved it?
