Ah bud, didn't work hey...
I get the error:
"Urgent Message
Please start EMERGENCY 5 using the 'em5_launcher".
-Instructions-
I think I found out why it wasn't working. When you extract the patcher, it should ask you what .exe you wanna use. Make sure you use the one with the smaller file size, and then it should work.
I hope this works for the rest of you.
