Problem after upgrade VBox 4.3 to Vbox 5.0

[satimis]

Hi all,

Host Ubuntu 14.04 running on SSD
VMs /Ubuntu 14.04/W80/etc on HD

HD /media/satimis/xxxx/VirtualBox VMs

After upgrade on repo and restart VBox Manager all VMs disappear

-> Preference -> General
Default Machine Folder /media/satimis/xxxx/VirtualBox VMs

All VMs are there

Please help rather than importing them one by one.

Thanks in advance.

Regards
satimis
