Bought this on ebay in 2010. Used it for a short period and didn't use it for about 1 1/2. Start to use it again and it would not activate with the code. Called rosetta stone and they advised it was a fake copy based on the headset and activation code. The customer service rep advised they deactivate it in 2012 when they found the activation code to be fraudulent. The seller is still active on ebay as digitald4. I lost $410.70 that I'll never recover.
