Plesk won't work after Update

[jimmygoodboy]

I log onto Plesk from my computer to maintain our email and website.
I was looking around on Plesk and noticed that it had two updates that
needed to be installed. So I clicked on one and gave it my email so it
would keep me updated when it was finished. It is 69 pages long, but it has an error on
page 69 that might be of interest. Now, I can not log on to Plesk. I get a
white screen after entering the login information.
