Hans,
don't know what you are doing wrong but, maybe slow down a little
to be sure what you are doing.

The chatline.txt file, if you definitely have the original Microprose CD,
HAS to be there. If you 'look' at the files on the CD, it should be the
last one at the bottom of the list.
If you have been using OAW before, you should not have any problem with the
new one. (V13) Only an 'old' version of OAW had the name of OAWProject.exe,
so somewhere you are getting your versions mixed up. The latest OAW exe is
named exactly the same as your subject to this post, OAWSelectV128V13.exe.
The download for OAW V13 is called OAW128V13UG.exe. Run it in a folder. It will
unpack and give you a folder called OAW128 and the OAWSelectV128V13.exe.
Place both of these in your new EAW root, and you are ready to use it.
The OAW128 folder is where you place your 'lettered' folders of items you load
with OAW. (T terrain folders, E eaw executable folders, F fm folders, etc.)
Just copy some of your favorite things from your old OAWUnified folder to your
new OAW128 folder.
I'm sure Jel will tell you more.
