Hi, after installing lcpdfr 1.0b on my desktop, i wasn't able to launch GTA IV because after the social club log a window would pop up and immediately say GTA IV has stopped working. Then a little window at the bottom would pop up and saying "Grand Theft Auto IV was closed" and its description said Data Execution Prevention had stopped it. Before installing lcpdfr, my game would start and run great, I am running windows vista. I run the game as administrator, i've installed lcpdfr multiple times, attempted manual install, attempted disabling DEP, attempted using the default option in like it was said in one of the topic, so idk what to do. I know i must post my computer specs but idk how if someone could answer that for me too. Thank you so much for the time spent to help me. I really appreciate it.
