Hi,

If you receive an "Invalid License" error when activating Studio One 2, It's possible that the version of Studio One you have installed on your system is the 1.0 version of Studio One.

1.0 is a separate software from 2.0. So, if you try activating 1.0 with your 2.0 key, you will receive an error.

Make sure that you have installed Studio One 2.0.

To install 2.0, login to your account (www.presonus.com/registration) >> My Software. Below Studio One 2.0, you'll see a list of downloads. The first downloads in the list are installers for PC and Mac.

Download the appropriate installer, then install. You can then activate using your 2.0 product key.

Thanks and best of luck!

If you get a message that says Melodyne is not compatible with Studio One, but the normal plugin version of Melodyne (the one with the transfer button at the top of the Melodyne GUI) is running without any issues...

Here is a workaround to solve the problem:

- Shut down Studio One
- Delete the folder "Studio One 2" from Users/<your name>/Library/Preferences/PreSonus (Mac)
- or delete the folder "Studio One 2" from Computer/System/User/<computer name>/AppData/Roaming/PreSonus/Studio One 2 (Windows)
- Start Studio One again
- Try again to open Melodyne with CMD-M (Mac) or CTRL-M (Win) on an audio event

How To: Manually Save Your StudioLive's Presets (Mac & PC)

Universal Control, starting in version 1.5, has been coded using a new framework

that will allow us to do some really cool things as far as product integration. In the process of

changing over to this new framework, the Backup files in the old VSL became incompatible with the

new version of the software. The Scene's and Presets themselves, however, are fully compatible with 1.5.2! Here's a workaround to saving a backup, just in case anything should go wrong during your update of your StudioLive:

1. Connect your StudioLive via firewire to your Mac or PC and run Universal Control

2. Click the “Get” button in VSL's Browser

3. Click the Up Arrow in the Browser window to move your presets to your disk

4. Close VSL/Universal Control

5. Go to your Documents/Presonus folder

6. Right Click (or Command Click in OSX) your StudioLive folder and Copy it

7. Paste your StudioLive folder on your desktop

at this time, you can safely perform your update to UC 1.5.2 without fear of losing your presets due to a power failure or some other unforseen issue. While performing the update you will be asked if you would like to Restore or Reset your presets. Choose Restore to have them automatically returned to the board after the update.
