MSDN describes the UnauthorizedAccessException exception:
The exception that is thrown when the operating system denies access because of an I/O error or a specific type of security error.
In a nutshell, Windows is preventing the compiler from reading your files. It's not immediately clear to me why it's doing that, but a quick search suggests your computer's antivirus software might be the culprit:

just make a change to one of your scripts, a change that of course doesnt affect your script, like putting a space at the end of a line. then save the script and the error should go away. at least it does for me. ofcourse your mcafee real time scaning should be off.
