Hello, Today I have installed GTA IV and had it working, I made a gamesave of the first mission, then proceded to install the latest version of lcpdfr, Everytime I try and start the diagnostic tool to see whether LCPDFR is working (as in game nothing happens) It proceds with an error message stating "LCPDFR Diagnostic Tool has stop responing". I am on version 1.0.7.0 and the game is legit. I have tried re-installing the game, the .net frameworks and everything, This is the report from the crash (multiple different crashes): Configure: Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: lcpdfr diagnostics tool.exe Problem Signature 02: 1.0.0.0 Problem Signature 03: 5505c37b Problem Signature 04: PresentationFramework Problem Signature 05: 4.0.0.0 Problem Signature 06: 51eea94f Problem Signature 07: 6b68 Problem Signature 08: ba Problem Signature 09: System.Windows.Markup.XamlParse OS Version: 6.1.7601.2.1.0.256.4 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 Check Installation: CLR20r3 Problem Signature 01: lcpdfr diagnostics tool.exe Problem Signature 02: 1.0.0.0 Problem Signature 03: 5505c37b Problem Signature 04: Diagnostics Tool Problem Signature 05: 1.0.0.0 Problem Signature 06: 5505c37b Problem Signature 07: 125 Problem Signature 08: b0 Problem Signature 09: System.MissingMethodException OS Version: 6.1.7601.2.1.0.256.4 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 Help on how to resolve this would be great Thanks James (jamester135)
