Blank page on viewing builds, HTTP ERROR 500 on viewing project, ClassNotFound

I just installed a fresh install of TeamCity 10.0.4. I created a project, a build configuration, and a simple build step using command-line shell to echo hello world. I can run this build and see success. I can even make it create a file and the file is being created.

When I click on the project on the main page, I get the expect tabbed project view. When I click on my build configuration within that project I get an HTTP ERROR 500. If I click back and then instead try to click on the build results, I am taken to a blank page with no tabs or any info at all, just the TeamCity menus at the top. I get errors in my logs both times.

I have pasted the logs below. Does anyone know how to fix these?

Thanks a bunch,

For the build home page, when I get the HTTP ERROR 500, this appears in my logs:
