Problems with the activation, please help. (The Witcher)

Hello Great Gurus of the computer world and Play Grounda. I had an unexpected problem. In General I have a license the Witcher: Complete edition, decided to establish, set, began to enter the serial number entered and an error with this text unable to launch the application in connection with invalid activation data in the registry. Inconsistent activation key. Reinstalling the game did not help, re-entering, too, wrote in 1C, but it seems to me that the answer I will not wait. So I pray for your help. Well, seriously, help please.
