Hey Sam, Yes. I did install GTA5 with the help of a friend. We managed to play the first scene of the story mode. Then once we had installed LSPDFR and created a charachter in the PD locker room it would freeze and go no further.
Since then, I have deleted all mods and re-installed GTA5. However without the help of my friend being present... I am a fish out of water so to speak...
Regards
David
