When a PC supplier installs Bullguard, they do not register this with a username or password, Bullguard then enters a 7 day Guest Trial Period. Once you enter your own username (email address) and a password of your choice, then the 90 day trial period will be activated. But as stated all questions can be directed to Bullguards excellent 24/7 support team, where they will gladly assist. If all fails, simply download the latest v8 60 day trial, uninstall your current version, install this latest v8 and register (assuming your have not already registered, if so register with a new email address to get the 60 days trial).
