My Macbook pro has a problem with cd and I can’t reinstall Cubase Studio 5. Is there any place I can get it officially ? I have got my dongle and everything.
You can try copying the contents of the install DVD to the desktop and running it from there. If that doesn’t work, you’ll have to contact your country’s distributor and ask for a new disk.
My laptop’s cd doesn’t work at all ,it isn’t the Cubase DVD that has the problem. So I need to find a way to get the install without plugging anything into my cd tray hehe 
You could try an external USB drive. They’re not too expensive. Might not be a bad investment if you don’t want to fix your built in drive.
Or use another PC to copy the contents of the disc onto an USB drive.
