Sibelus wont launch

[Noobie007]

Hello,

recently I changed the processor on my aging Mac Pro and now Sibelius 5 and 6 wont open. It just crashes all the time. What can I do???

Sibelius might be thinking you are on a different computer. That's basically what changing the cpu does. I would try to Restore Permissions first. That is under Disk Utilities on your hard drive.
You can reinstall if you haven't used both your installations. Otherwise you would need to put your old cpu back in, de-authorize, reinstall new cpu, re-authorize.
