I'm having trouble editing the gta3.img for LC with IMG tool. Every time I try to edit the files it comes up with an error saying they are in use. I have no version of GTA open so I think it's a read-only problem (the LC folder is set to read only).
I have tried multiple times to change it to not read-only but it immediately changes back by itself every time. Have tried the whole rockstar games folder to no avail. Any advice?
