I'm fairly new but familiar with the concrete5 file structure. I have a problem whereas I go to my website, I am presented with the login screen. I login and then I see my site. the editor etc works, but when I try to access my dashboard, I get this error. I've edited out the location for security reasons.

Fatal error: Class 'DashboardHomepageView' not found in /home/(user)/(mywebsite).com/concrete/controllers/dashboard/controller.php on line 8

If someone has a moment and knows how to fix this, I'm on IRC in room concrete5 - and would love a hand. thanks!
