Okay, I thought I did that already, but tested again just now. Doing a clean portable install, I then applied TK17VXF_Update1.00p, and fine as before. Then I installed TK17VXF_Update1.01P_KE1 over it, and still get the issue with loading models.
I also tried it before, where I started with p, then q, then r, then the KE. Same issue with loading models.
I have not even applied Hook5 yet when testing the KE over the p update, so Hook5 doesn't seem to have anything to do with it.
Is it possible that the Update P file you are referring to is not TK17VXF_Update1.00p, but a different one not contained in the Updates folder, which should come after 1.00r, but before 1.01P_KE1?
These are two different title screens I get, where the first is anything before KE, and the second is the one with KE:

A friend of mine showed me his, and it looks like this:

I don't know how he got his title screen like this...since I thought I applied the p update, and it just looks like the first screenshot above.
