after downloading Sound Forge Audio Studio 10.0 I lost the activation/registration number to activate the software. I paid for the software but now can't use it and Magix is not helpful to solve this problem. Frustrating!
Log into the Magix Service Center and go to the 'My Products' page your product serial number(s) should be listed there. Use the same email address you used when purchasing... assuming it was Magix.
