Restoring Full Mail Backup

My laptop recently died with a mainboard failure.

I had two backup jobs on the old laptop - one to backing up my files, and one to backup my mail.
I bought a new laptop and restored my files (photos, docs etc) successfully. However, when it came to restore my full email backup, the executable fails and the application terminates.

The old laptop was an HP with Vista Basic, the new a Dell with Win7 Premium.

Is there some additional config I need to be able to restore the mail backup successfully?

Many Thanks


Please create a dump file when the executable crashes.
