Suddenly, i lost all Geny motion emulators (maybe after upgrading to Geny motion 2.2, not sure) and when ever i download a new virtual machine or emulator i get the \"failed
UPDATE
Some VirtualBox version are not compatibles with genymotion: review FAQ Genymotions in https://www.genymotion.com/help/desktop/faq/#compatible-virtualbox-versions
If you see the log file of Genimotions you'll find this:
VBoxManage.exe: error: 'Linux_64' is not a valid Guest OS type
The problem is the version of Virtual Box, I thought I had the last version (4.2) because virtual box said me that it was the lastest version, but it wasn't true: The last version actually is 5.0.20
I've installed the last version (5.0.20), and ova is ok
