I installed the new version 1.0 today after having the old version. I had no problems with my old version, everything loaded fine. I successfully installed the new version and the components it came with and then right clicked on the GTA4 Launcher i had always used and clicked run as administrator. It signs me into the play online thing and then pops up the windows error that GTA 4 has stopped working, which i then click close. At this time an icon pops up stating that DEP closed GTA 4 . I went to the setting and checked the GTA 4 files to allow it to work under DEP. I then restarted my computer and tried it again and it still does the same thing ? Anyone else having this problem ? I am running Vista. Thanks
