something is wrong with the torrent link. I downloaded it with torrent and then when i got everything installed turned out that my version of the game is 87.0 when the server's is 88.1. pretty weird, though everything was saying that it's 88.1
UPD: so, i downloaded the .exe file instead of .torrent one. and everything went the same way. i installed the mod after i uninstalled the previous version, and same thing happened : the instalator truly believes that it installs 88.1 version of the game while the version being installed is 87.0. i rly don't know what to do
final update : thx to antonio and forex14, i found dslauncher and it justs updated the game right to 88.6
