July 2, 201213 yr I am trying to unlock the last part of Liberty City I need, both for the achievement and to increase my patrol route when I launch LCPDFR. I am currently trying to unlock Alderny which means having to do the Bank Robbery mission. However, GTA IV always crashes during this mission and I am, obviously, unable to complete it. Sometimes it'll crash before I rob the bank, other times it'll crash after I have robbed it and am fighting through the army of police and NoOSE officers. It doesn't tell me why it crashes, it just says 'GTA IV has stopped working' which is frustrating. I can't patrol Alderny without completing it. I know I could patrol it by visiting a police station in another part of the city and driving there, but having done that once already, I received no call-outs whilst doing so. Has anyone else here experienced this issue but has found a way to remedy it? If so, could you please share it with me? I had thought of the Diagnostic Tool, but I believe that only finds faults within LCPDFR and not GTA IV itself. Thank you for reading this and I look forward to your replies. Note: I posted this in the GTA IV Support section as it has nothing to do with LCPDFR. It is the game that is crashing during the mission. If this is somehow in the wrong place, I apologise. Please do not give me negative reputation for it. I did do a search for other topics covering this issue but I found nothing.
