I got this new 1.66 update for arma 3 and my exile server that i play is in 1.64 so i cant login anymore
Wrong place. try getting support from the server owners
You need to revert Arma 3 to the previous version.
In Steam Library right click Arma 3, click Properties
Click Betas tab
Enter "Arma3Legacy164" (without quotes) into beta access code and click "Check Code"
Select "legacy - Legacy Build 1.64" from the drop down and click "Close"
@Sampson Thanks for the help
