hey there, i bought gta v games on demand a few days at my dad's, and it worked fine. I played it for a couple of days... then i come back to my mom's, and it wont work. when I download the game, and start up gta, it works fine. but the problem is, once it downloads ONE OF THE GTA PACKS, that's when it says disc unreadable. a user on the gta v forum told me to license transfer, delete gta, and redownload it, and that might work. im doing this now, but give me other solutions just incase it doesnt work. thanks.
