• Select General.
• Get your BullGuard product ID from the lower part of the interface.
To find the Computer Name right-click on Computer and select Properties (for Windows Vista, 7) or right-click on the Windows button and choose System (Windows 8, 10). In the window that opens you should be able to locate the Computer / PC Name.
Finally try to re-login with your BullGuard username (email address) and password inside the BullGuard program on the computer which needs to have the BullGuard installation active.
