Root Downloaded system update and root is no longer working

[Early]

I recently purchased a HTC Wildfire S from metropcs and proceeded to successfully root it. I did it especially to use the wifi hotspot apps. This past week I allowed my phone to perform a system update and after it had finished, my apps no longer detected a root, and superuser hasdenied access to each and every app. I attempted to root again with htcsupertool version 3, however, it now says this:
