Losing files upon export

Ok deve开发者_Python百科lopers needing some help here. I am working on a MVC 3 project with another person. My code runs great and builds, but even though he updates his code, his won't build and run. I tried to export it but over 1.2 of the files are being exported.

I'll show screenshots of what's in the bin folder I have and what gets exported.

First the bin folder I have in the project. Anyone know why this is happening and how I can resolve it?

Now the exported bin

Anyone know why this is happening and how I can resolve it?!

Have you added all the missing files that you expect to be in subversion? You have to do an 'svn add' followed by a commit for them to show up.
