I just flattened and rebuild my home system recently, which had several VirtualBox VMs with snapshots. I backed-up all the VMs, VDIs and snapshots by copying the entire folder to an external drive. After the rebuild, I restored the folder to its original location, but when I open the VitualBox UI I get the error message:

Is there something I'm missing? Do I need to manually edit the .vbox files?

My host system is running Debian 7.4 and VBox 4.3.8

Run a search on your machine for a hidden VirtualBox directory ".VirtualBox"

Remove this (or move it), then restart the software.

All should then be working.

The fix for me was to remove the ~/.VirtualBox folder, restart the VBox client program, and then Add all the VMs manually via the Machine menu –  Jonas Gorauskas Mar 14 at 18:26
