Sample Rate

Can anyone Help!!! Computer mother board went down. Loaded Cubase 5 onto another computer. Managed to save all my cubase files from a backup hard drive. Loaded them into cubase on new computer and get massage
“SAMPLE RATE COULD NOT BE SET THIS MAY BE DUE TO THE SAMPLE CLOCK BEING SET TO EXTERNAL SYNC”
The tracks will load but when I play them they are all out of time. Has anyone any ideas what I can do??

First thing I would check is the driver you loaded onto the new computer. If you can open up the driver interface and make sure it is set to internal sync and not something like ADAT or other options. Also go into your project setup and ensure the sample rate is set to that which you recorded original tracks to as not sure what cubase 5 would do as I am on 8.

Good luck
