I can play with GTA 4 without any problems, but when i installed LCPDFR, first give me the dsound.dll error, i read on google, and i fix them with 'run with admin' but then GTA wan't start. I'm on Windows 8.1... And if i disinstall LCPD, GTA come back to work, i really don't know what can I do... My LCPD is 1.0c, and for install it i used the automatic install. And GTA with 1.0.7.0
