Ill try that! One thing i thought about was i used offline authorize on my winxp system (which works fine but) and online on my laptop.My internet is super slow so maybe it didnt authorize all the way,leaving it in demo mode without the ability to save.Imma try offline unlock and see how that works
Really?

You just didn't write
WinXP? This may or may not be an issue. But I don't think that OS is supported.
Regardless....
Go to the 'About MPC' page. When you open it up, it should display software version and whether it is registered.
When installing the Ren, there are three installs you have to do. The driver must be installed first and then the actual MPC software and library.
First go to Windows Control Panel and Uninstall Program section. Disconnect your Ren. Uninstall:
1. MPC Renaissance driver
2. MPC 1.0.0
3. MPC Factory Content
After uninstalling these shut down your computer completely and d. Then turn it back on again.
1. Insert the MPC DVD and click the installer
2. Install the MPC Renaissance driver. During installation, it will ask you to connect your Ren to your PCs USB 2.0 port (make sure the Ren is powered on). After a few moments, the installer will ask you to disconnect the Ren from the USB port and then prompt you to plug it back in again. This should complete the driver install.
3. Next install the software and the factory content. Once this is done, launch the Ren software by double clicking the MPC icon. **The Ren should be turned ON before opening the software**
4. If the software isn't registered/authorized, there should be a message telling you to register it. Follow the instructions for activating it online.
This process should work. Or there will be a message indicating you exceeded authorizations.
