Not for nothing, but I don't have free time to spare to examine your entire admin folder in detail.. A quick glance at the file contents and I noticed that I didn't see an orders.php file..
I have provided you with enough guidance as to the nature of your problem and possible fixes.. My suggestion at this point is for you to back out all of the Edit Order files and edits you have made and start over..
The error you have is either due to an incorrect/incomplete Edit Orders install or because there is another issue in your store which is creating the missing language file errors. Edit Orders was tested by a number of folks prior to being submitted to the downloads, and it works PERFECTLY out the box..
