Can't play game, "Session error" "BattlEye has encountered an error"

[LV858]

Ok, so I purchased this game last week. Upon installing it, I was able to play the game. I was playing in the "play mode" and I was not running into any enemies. I made a post on here and it turns out that I was in the wrong mode.

I needed to play in the "multiplayer" mode. After switching to the multiplayer mode, I have to join a server and downloaded the requirements for that server. Ever since I did this, I am not able to play the game at all.

Even when I tried to go back to the "play mode", i keep getting kicked out with an error message. So now I cannot play this game at all.

In the "play mode", I am getting this message "Session error, Internal error has occurred"... Then when I click on the "multiplayer mode", I get this error message "Session error, BattlEye has encountered an error".

Anyone know how to fix this issue? If I delete this game and download it again, would this fix the issue? Anyone help is greatly appreciated.
