Failed to acquire the VirtualBox COM object. The application will now terminate.

After successfully installed VirtualBox, when I try to open it, a Critical Error Window pumped up says that The application will now terminate.
it says that cannot register the hard disk because the hard disk with UUID already exists. The Result Code: NS_ERROR_INVALID_ARG (0x80070057)

but I have already deleted that hard disk it said I already registered.

How to solve this problem?
