A pop-up blocker is installed on your PC. It prevents the relevant window from opening. Please deactivate all pop-up blockers and try again. Please note that, apart from your browser, pop-up blockers are often installed in toolbars such as Google-Toolbar or Yahoo!-Toolbar, and also very often in "Personal Firewalls" such as, for instance, Norton Internet Security. You definitely have to deactivate all pop-up blockers so that everything can work again.
