When I open the language patcher I click patch and a little bit after it says "Could not open output file" and after I click ok it says "Patch failed, view readme.txt" Please help, i had put the 3 things into pak and i unchecked read only and i dont know what to do.

Run as admin?

i do run as admin. am i suppose to put the read me txt in the pak folder?

Yes

then wats wrong??

My patch didnt change a thing.

You copied all the stuff from the zip folder to the pack file right? and uhchecked the read-only in lang0.pak?

yes i did all that but it still says the same thing

Look at the top of Techincal forum part and go on ssjkiego's guide to English Patch helped me out :P To fix that Output file you got to right click lang0.pak go to properties and untick Read-Only :) hope that helped
