Won't accept SN
 

I created a Full copy to an external drive, replaced my internal drive, booted from the external drive, now ready to restore to the new internal drive and SuperDuper says my registration is invalid. It was valid when I backedup lastnight. This means I can't copy without password authentication.

I have that s/n in my 1Password and it matches the one in the dialogue box that's pre-filled. My other apps 'remember' their registration codes while booted to the external.

Any ideas? Kind of defeats the purpose of backing up with SuperDuper, if once you do, it 'forget's it's registered.

I'm booted now off the external drive with the internal drive sitting in the computer waiting to be restored to.

Edit:
MacBook Pro
2.2 GHz Intel Core 2 Duo
4 GB 667 MHz DDR2 SDRAM
10.6.6
500 GB Drive

Check that your time/date is right. Note that the serial number and name must match the ones in the receipt...

After quitting the app and restarting it, it seems to have taken the SN. May have been the time/date thing needing to finish 'loading'. I've got my new 500 GB installed, restored too and the MacBook Pro back together.

Thanks.
