Random error in config

[blakefire]

In the configuration for this plugin it seems to get this error out of no where.

Warning [2] require(/home/gfxcafen/public_html/mcmines.com/<admin Directory>/modules/config/threadfields.php) [function.require]: failed to open stream: No such file or directory - Line: 488 - File: TQaB!!s/index.php PHP 5.2.16 (Linux)
File Line Function

Fatal error: require() [function.require]: Failed opening required '/home/gfxcafen/public_html/mcmines.com/<admin Directory>/modules/config/threadfields.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/gfxcafen/public_html/mcmines.com/<admin Directory>/index.php on line 488

It was working for a while, No, I don't know when it happened I just noticed it recently.
