Your validation seems really weird. I'm sure it is the cause of your problem.

First of all, you seem to have installed EB into the wrong directory, as tons of vanilla files are missing, but also you have tons of changed vanilla files. Possibly you have not patched RTW to 1.5 before installing EB?

Secondly, your language is not entirely clear, but it sounds as if you first installed EB 1.0 and then EB 1.1 on top of that (and the validation supports this). This is not a good thing, as 1.1 is a full installer and not a patch. You need to scrap this installation and start over:

* Get a clean 1.5 RTW (outside Program Files, mind you)
* Install EB 1.1 into that RTW folder
* Install the Trivial Script
