Troubleshooting Compiling

[eherman3]

To whom it may concern,
    I have downloaded files off of our server at University at Buffalo 
onto my personal computer and as I compile them, I get this error. It 
will save changes that I make to the files but it won't compile them. 
Not only does this happen to my files from the school, but a test app 
was created and the same error was recieved. I'm told it is because of 
a file called prj.el needed for compiling. I have searched my computer 
for this file and minus the ones found in the emacs installation 
folders, its not found on my computer. I don't konw what else to do.
Please help ASAP. Thank you.
