title: Team Foundation Server deleted local files after I undid pending changes
body: <p>I have a big problem! I made lots of changes to my c# project on my local machine. I added, deleted, modified, etc. It's been about a week since I've checked anything in to TFS so when I did a check-in, TFS threw some errors saying it couldn't find some files (ones that I had deleted, ok that's fine). </p>
  
  <p>So now what I did was really stupid!
  I undid all pending changes in TFS for that project and it totally wiped everything on my local machine back to some earlier version that I had checked in last week. All my files that I had worked on this last week were gone! What do I do!? is there any way to get my recent stuff back or am I screwed?</p>
