i try an other way.
on a fresh install of ET legacy, it was impossible to connect to FA server.
I choose Silent for exemple and get the same error with a missing dll : ui_mp_x86.dll
I just copy this dll from ET folder (in programs files) to ETlegacy folder in C:\Users\Ecoban\Documents\ETLegacy\silent.
if you don't already have ET: install it => https://fearless-assassins.com/files/file/774-enemy-territory-full-version/
Gildas,
I had the same problem with Legacy and NoQuarter server : i have copied files (pk3, dll) from Etmain folder/silent to the legacy one. And now it works.
I also had a problem with resolution (partial screen...) when I upgraded.
And thx Aziph10 for the ETlegacy solution
