I bought the Vegas editing bundle from Humble Bundle today, and while I was trying to redeem the Vegas Pro 15 software, the registration crashed and closed out. I opened it back up and it says the code has been used. I uninstall the program and reinstall it, but same issue. I log into Magix.com, and it says Vegas Pro 15 has been registered to my account. But everytime I try and launch it, the program keeps asking for another serial number. I would love to use the program that I bought. It's just frustrating.
