True Image 9.7 Workstation - Bootable does not see disks on Dell Opitplex 390

Hello,
I have true Image 9.7 Worksation and the bootable media build 8.398.
Everthing has been great so far, but just got a Dell Optiplex 390, now when I boot from the CD and try to do a backup, I get the following error:-

E000101F4 ... has not found any hard drives.

Any help please?

Is my version to old?
