It could be a few things. Blank McAfee windows are usually a sign of a beta version of Internet Explorer being installed. Whether or not you use IE is irrelevent as McAfee does. If that's the case please uninstall the beta and install IE9 from Microsoft.
Even if you don't have a beta but actually have IE8 please update to IE9.
If you already have the final version of IE9 then try opening it and going to Tools.Internet Options/Advanced , click Reset, Apply and OK any prompts.
Close and reopen IE and go to Tools/Manage Add-ons and re-enable any add-ons you need.
If that doesn't help then as I see you are possibly at U of Calgary are you behind a proxy/firewall? The Uni IT people should be able to advise you on that and how to configure things. McAfee does not work well behind proxies.
The 3rd idea would be that McAfee is corrupted somehow and the best thing to do is to uninstall in the normal manner via Control Panel/Programs/Uninstall a Program.
Then run the MCPR cleanup tool listed under Useful Links at the top of the page.
Reboot and reinstall from your online account.
Lastly I would hope that your Windows 7 is SP1? (Check by right-clicking Computer on your desktop or in the Start/All Programs menu and selecting Properties). If not then you need it and there are some helpful hints for that here: https://community.mcafee.com/docs/DOC-2205
That also might fix this issue.

I think it is most likely IE9. After reading your comments, I unistalled it and now am having a heck of a time reinstalling it. I keep getting an error. I'll let you know if I ever get it installed and if that doesn't fix the McAfee issue.
Ouch, well good luck ;-)
Finally got IE9 reinstalled but cannot find the MCPR. The link above goes nio where. I searched but couldn't find anything. Thanks.
Thank you for all your help. McAfee is back up and running. I did it ffrom home so I have a feeling something must have gone awry at the UC...
Glad you are OK now. ;-)
