Survey does not appear after login

I inherited Ultimate Survey Advanced 7.1 from a previous webmaster. I was recently notified this survey was no longer working. The previous webmaster fixed the connection string so the survey could access the SQL database.

However, upon a successful login, I only see the header for the page but nothing else. I think part of the issue is the survey not seeing the style sheet since there is no formatting on the page. Since I am not an ASP programmer, I do not know how to diagnose the issue and restore the functionality.
