aapt.exe location incorrect

I downloaded and unzipped Tasty (for Android) from the Xamarin.Studio home page.

I opened it, did a Clean, and then a Build.

The Build fails with the following error:

C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2,2): Error MSB6004: The specified task executable location "C:\Program Files\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\aapt.exe" is invalid. (MSB6004) (TaskyAndroid)

I checked in the SDK (4.2.2) and aapt.exe is actually in ....sdk\build-tools\17.0.0\aapt.exe

I previously built a new app using the "wizard", compiled and ran it right before I tried Tasty.

How do I fix this problem?
