[FIX HERE] "server is running an incorrect version of server side application"

[chengysogood 0]

For those of you who tried reverting your version and ruined your game and can no longer join servers (be it 1.7.1.1 or 1.7.1.2), you need to follow these steps to fix your client.

Navigate to your ARMA 2 operation arrowhead folder and do the following

1) Navigate to Expansion > beta

2) copy "arma2oa.exe"

3) Navigate to Arma 2 operation arrowhead folder

4) replace "arma2oa.exe" with the copied version from step 2

5) Use six launcher to try rejoining 1.7.1.2 server and it should resync/update/verify and allow you to rejoin these servers.

Have fun

Umm yea... It probably works because rocket and crew were already implementing a fix database side. http://www.dayzmod.com/forum/showthread.php?tid=9124&pid=142250#pid142250
