Unable to open VirtualBox

Hello,

I have to submit an assignment that needs to be done with VirtualBox, but since yesterday it won't open anymore and displays an error message:

""Failed to acquire the COM object of VirtualBox.
The program will stop.
Error in C:\Users\Katana\.VirtualBox\VirtualBox.xml (line 25) -- UUID "{00000000-0000-0000-0000-000000000000}" has zero format.
F:\tinderbox\win-6.0\src\VBox\Main\src-server\VirtualBoxImpl.cpp[622] (long __cdecl VirtualBox::init(void)).
Error code: E_FAIL (0x80004005)

Called function: IVirtualBoxClient {d2937a8e-cb8d-4382-90ba-b7da78a74573}""

I have already tried uninstalling and reinstalling it, I even reset my settings/applications, but once reinstalled, the same message appears.

Can anyone help me please?
