php errors on non-wordpress doc

I have a directory in which I store files that I reference in my blog. They are generally.doc or .pdf files and not part of WP media files. When a file from that directory is accessed, it should display just as the document without any site formatting at all.

However, now when I attempt to access a file I get a number of php errors pointing at FV Flowplayer, and the file will not display. I am confused and would appreciate any information to help me resolvee this issue.
