[SOLVED]Problrm with Virtualbox after upgrade

After the last upgrade Virtual Box to ver 5.0.16, it is not possible to start WIN XP virtual machine, previously working properly. The error is below.
Any idea what to do? I try to reinstall VirtualBox but it does not help.

If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs. If this error persists, try re-installing VirtualBox. (VERR_PDM_DEVHLPR3_VERSION_MISMATCH).
