When I registered my movie studio 15, I accidentally left off 2 numbers and now it says that "This serial number has already been registered to another email address. Please contact MAGIX support. Can you help please?
Probably only Magix Support can help you but please clarify your problem:
Did you miss the numbers off the email adress or off the serial number?
What exactly are you trying to do when you get the error message?
It asked for an email to license it to, and I messed up that. So what I'm thinking is, can I uninstall it and re-install it to the correct email? or do I just need MAGIX support to do this?
I assume by "It" you mean when you installed VMS you were asked for an email address to register it. You gave an incorrect address. What then happened? I don't know how the system works but possibly Magix then set up an account for that incorrect address (unless there was an existing account for that address) and would have asked you for a password for creating the account. If this didn't happen but you simply got no further then yes try uninstalling then reinstalling, or better still see if you have a Windows System Restore point you could use.
If you did set up an account then go here and enter the incorrect email and password you used. When in go to 'My Products' and find VMS15. Check it is showing your correct Serial number, click on 'Show more details' and under 'Device name' 'Deactivate' the registration. Hopefully you should then be able to start afresh and activate VMS with your correct email address.
