I have an update.

I just deleted and reinstalled TPP, and it seems to be working now. My website didn't disappear this time, and everything seems to be in order...

I am so sorry that I can't offer a solution to anyone else who's page went blank, because I don't know what, if anything, I did differently. But, I can tell you exactly what I did:

1. uploaded the files into the "include" file in the "admin" file in my store. (Any files that didn't exist in the "include" file, I uploaded the whole file.)

2. changed the YOUR_TEMPLATE name to the name of the template I'm using, and uploaded those files to their respective places.

Now, I did that the first and second times I tried to install. The first time, the formatting of my website went all haywire. The second time, the website disappeared altogether. I must have done something wrong the first two times -- I wish I could tell you what.
