Updated to Android sdk r15, but now I can't use anything
<p>I'm not sure what I did wrong, but I'll try and give as much information as I can.</p>

<p>Yesterday, I updated a few things in the manager, with one of them being sdk r15. Now, I'm not sure what was updated because I believe there is the sdk 15 and the adt plugin r15. In any case, one of them was updated. I didn't restart and continued to work without any problems. However, today my emulator stopped loading the app I was testing. I restarted eclipse and was thrown this prompt:</p>

<blockquote>
  <p>"This Android SDK requires Android Developer Toolkit version 14.0.0
  or above.  Current version is 12.0.0.v201106281929-138431.  Please
  update ADT to the latest version."</p>
</blockquote>

<p>Currently, all of my projects have error symbols next to them. I then proceed to click the AVD manager, which I'm given a prompt that says: </p>

<blockquote>
  <p>"The location of the Android SDK has not been setup in Preferences."</p>
</blockquote>

<p>I go to Preferences and see that the sdk path is pointing to the correct folder. I haven't changed anything so I dont see how the path could be a problem. </p>

<p>What happened? How can I get things working again? Perhaps, the update did not install everything properly? </p>

<p>EDIT:
By the way, I "apply" and "ok" are greyed out in Preferences no matter which folder I choose.</p>
