I'll get these instructions added to the readme's Troubleshooting section.
I tried to read the troubleshooting section, but it was way over my understanding. Didn't even understand it if was explaining anything close to what I was experiencing.

The checkout starts after clicking the checkout button on the Shopping Cart.
Did you enable One-Page Checkout Debug in Admin>Config>One Page Checkout Settings? If so, you can find which elements are missing in the log files in your logs folder, also very useful when you get blank pages.
I guess you did not upload some files correctly.
Yes, I did enambe the One Page Checkout s under Admin > Config > One page Checkout
Here is one of the several identical logs that was produced.

I am not sure how to interpret this message, but I checked and the file tpl_main_page.php is not missing. Does it say that it has to be edited?
