WP-Cache Plugin Issue – Unfixable?

Everything was going fine with my web site until about a week or so ago. Now, I can’t log in to my WordPress User Panel, and can’t view any of the pages on my site collegeandfinance.com

The error I get is always the same when i go to http://www.collegeandfinance.com/wp-login.php:

“Warning: main(/home/.mupps/scotsworth/collegeandfinance.com/wp-includes/cache.php) [function.main]: failed to open stream: No such file or directory in /home/.mupps/scotsworth/collegeandfinance.com/wp-settings.php on line 217

Fatal error: main() [function.require]: Failed opening required ‘/home/.mupps/scotsworth/collegeandfinance.com/wp-includes/cache.php’ (include_path=’.:/usr/local/lib/php’) in /home/.mupps/scotsworth/collegeandfinance.com/wp-settings.php on line 217″

I’ve been told that it’s a cache issue…but I don’t know how to uninstall the mod since I can’t log into the user panel. I have tried by deleting the wp-cache files from my directory (as I can still get into that) and it has done nothing. Any help or suggestions would be greatly appreciated.
