OP of the stickied help thread here, first off, you could have posted this in the stickied topic because one of the reasons I made that was to save the forum of these threads that will consequently make you look like a dumbass for not posting to the most obvious thread on the board....
Anyway, you need to make all the file to READ AND WRITE not Read only. Do that, I'm 78.4% sure that will work for you. It's not working because you didn't read OP of the stickied thread carefully enough. Okay, that's my two cents, carry on, preferably in the sticky thread.
