Vegas Movie Studio 17 Platinum = Error Code 14. Magix support said Amazon gave out the wrong Serial Number> Amazon tech support (Andy) tried to contact Magix with no help> Amazon said to contact Magix. To resolve this ping-pong between Magix and Amazon, I canceled the Amazon download order, took the refund and paid Amazon to send me a CD with the Vegas Movie Studio 17 Plat. Then I used that Serial Number to register the previously downloaded and installed program from Amazon. It works fine now! The net: if you order this program-version 17 from Amazon, order the program content on Compact Disk (CD) with hard-copy Serial Number.
I Suspect that Amazon Program Download group mixed up the serial number form ACID Music Studio and sent this serial number for Vegas Movie Studio by mistake. However, neither Amazon or Magix were able to correct the problem and send me a correct serial number.
