For the record, we're planning to improve the experience with Camtasia and software keys like what was done with Snagit, where you can (optionally) sign into the software and your key will be populated for you if you have it associated with your TechSmith Account. Snagit currently operates this way, but it's still in the works for Camtasia.
I bought camtasia on steam about a week ago and had no problems but now its telling me 'This copy of camtasia studio may not be genuine TechSmith software. If obtained from a third party seller, it may have been tampered with and couldpossibly contain malware. Immediate action is required to resolve this issue or enter a valid key. Camtasia studio will now close' Now this really pisses me off because i know i bought this legitly and now i probably will have to buy it again:( Do you guys have a suggestion or have had the same problems if so pls tell me!
