How to re-enable S2A?

[mwalt2]

So I installed Pocket Shield to try it out and ended up not liking it. During the set-up, it disabled the black S2A that was cooked into the ROM I'm using. Now I am stuck with the standard WinMo phone canvas. How can I change back to the S2A? I realize I could probably install a cab, but I don't really want to use up the space when it seems like a setting somewhere in the registry will get the black S2A phone canvas back. Thanks.
