Unable to start the Genymotion virtual device.

Hi there,
I cannot configure VirtualBox again. First time I used it worked wonderful without any error. When I want to use it again this error message box appears on my desktop and I can’t configure it right. How can I configure VirtualBox again? Is there some standard steps for this?
Thank you!

VirtualBox can’t run the virtual device.
Try to run the virtual device directly from VirtualBox to check for issues.
