Actually, what I ended up doing was googling 'isotanium ots2' and then downloading an OTS2 version of isotanium from this website I found, http://www.litestep.co.kr, and then I played around with the paths a bit, and everything worked fine.

By the way, there's now an isotanium2! It's a little bit better, to the max! (www.litestep.co.kr)

Thanks for the help.
