title: Why would my play framework say wait for a .sbt lock to be available?
body: <pre><code>[Sally] $ run
  
  [info] Updating {file:/Users/MyName/Desktop/sally/todolist/}Sally...
  Waiting for lock on /Users/MyName/Documents/play-2.1.3/repository/.sbt.ivy.lock to be available...
  </code></pre>
  
  <p>Sally is my project's name. I am learning how to use play. Yesterday It was all awesome. Today when I woke up and opened my computer, everything went to hell. I kept seeing this message when I try to run the program.</p>
  
  <p>What is this lock anyway? Should I uninstall/remove the framework and reinstall it?? (Btw how do I do that?)</p>
