Realized I didn't include how to make streamlabs read from a text file. Just create a new text object in your scene and click the "read from file" then path it to the corresponding player1 or player 2 file.
Follow me @iamthekolossus on twitter and at Twitch.tv/iamthekolossus
Copy paste this into response and change things to fit your stream and textfiles.
$overwritefile("C:\thepathtoyourfile\filename.txt","$msg","Success message here","Failure message here ")
