I hadn't tried pi^2.dat before, but I loaded it up and it works fine for me. Are you sure you've got a tileset with a graphic for the iceblock? I actually ran in to that very problem as I was testing it to make sure...
It may also depend on the 64-bit patch in some weird way. I haven't looked closely at either of these since I wrote them a long time ago. I already have patch files (somewhere) I could commit to the repo that do the same thing... but I could very well have done something wrong somewhere.
Edit: as for an EXE, this is all only tested on Linux for the moment I'm afraid. I don't have much experience with Windows and while I could probably come up with a patched EXE, I wouldn't really be able to test or verify it.
