I just installed GTA 4 on my new PC and I am playing Single Player and Multiplayer smoothly for quite some time. Then I installed LCPD:FR and started the game. I took a car and was just going to move and my GTA 4 minimized. I tried to Maximize it again but it didn't. Instead a DFA error stating "GTA IV FATAL ERROR: DFA did not initialize properly. Please make sure you are using LaunchGTAIV.exe to launch the game" came up.
When I uninstalled LCPD:FR it started working again. I have 1.0.7.0 Patch and regular GTA 4. Please help me, because I really want to play LCPD:FR.
