title: TFS - undo merge after get latest
body: <p>I did a search on this issue and found a lot posts and questions but none seems to target my situation.<br>
  I had pending changes and i did "Get Latest", i got the conflicts window and wanted to resolve them, so i did a merge as i wanted to keep both my changes and the server's new code. but i forgot to check the block of codes and i just clicked merge (did not  checked in yet!).  i had a conflict on one of the <code>cproj</code> files and now i lost some <code>.cs</code> files as well.<br>
  I think i lost both versions of code and i want to go back and do that merge all over again and do it right, but i don't have a time machine! :)<br>
  Any help would be appreciated. </p>
