hello Y961 XBU
there's some recommended step, as in the included ReadMe.txt, wich are:
Installation instructions:
- ** It's recommended to make a full backup of the OpenTTD instalation folder **
- Extract "openttd.exe" and "lang" folder to OpenTTD instalation folder (usually in C:\Program files\OpenTTD). Overwrite them, if necessary.
- Run the game, enter openttd.btpro.nl website info (Username and Password) in OpenTTD Intro menu (username and password are set separately by community).
- Click in the "BTPro Login tool" ingame to login into your account automatically (available too under own nickname in Client List)
the 1.5.0 versions are:
32
and
64
(choose the correct one, depending on your system)
Edit: check

for more details about BTPro client
the above step at
bold is very important, because that's the executable to run.
note: we also recommend create an empty "openttd.cfg" file in same folder where is the openttd.exe (that will allow you have different versions and each one with own settings)
Hope it helps
