REMEMBER ALWAYS MAKE BACK OF THE FILES BEFOR YOU CHANGE/EDIT.
1.Go to your combat arms folder.
2.Go To HSheild
3.Go to Update.
4. Delete ( Make back up also) Of AutoUp
- THESE STEPS MAY NOT LET COMBAT ARMS START, SO MAKE BACKUP FOR THESE )
5.Go back to Hsheild
6.Find HSUpdate ( Delete and make back up )
7. Hack away for no more HSheild updates =)
If It Dosen't work for you just put your back files there and it should work fine anyway.
( Did it with mine few minutes ago =) CA is still running fine on mine )
