Hi, Thanks very much for reading this post.   I'm not too sure if the IV Diagnostics software thing supports LCPDFR 1.0.  I installed LCPDFR via the automatic install, and I ran the diagnostics tool, and got the following:   I also got GTA IV: ASI Loader not found.   My problem is, when I start GTA IV, I press ALT + P to start LCPDFR 1.0, but get nothing?  Nothing happens?   Thanks for your time.   Cheers. Alex
