Dreamweaver 2020 JavaScript error

[meagangramlin16]

I was just on Dreamweaver last night and everything was fine. I did not update it or anything. Today when I got on, I got the following error message: 

        While executing onLoad in UpdateBootstrapVersion.htm, the following JavaScript error(s) occuerd:

         Infile "UpdateBootstapVersion":

         updatBSVersion is not defined.

My Dreamweaver runs on Windows. I tried resetting the preferences like Adobe suggested, but the error message still pops up. I have a midterm due Saturday and I need Dreamweaver to finish it.
