The game loads fine and shows the server list with the only issue being the message on the screen saying I'm playing a modified game (even when I selected the "play without mods" option from the launcher).
When connecting to a server (I tried a few different ones) the game shows the loading screen saying loading in x seconds and then quits out of the game to a Battle Eye install window. If I click on install, it quickly installs and then nothing happens. If I click Cancel, a window pops up saying the game has exited unexpectedly.
See attached file for dump report for when I hit "Cancel" in the Battle Eye installer window (auto-generated)
