Here's the log file and as you can see, i've messed with different paths and version of mame prior to installing, but the mame I'm using is clean in its own directory. Daphne runs fine and exits fine, its mame thats erroring. 07:27:22.2 3/11/2010: GameEx: Version 10.41: Starting Log 07:27:22.2 3/11/2010: Operating System Platform: Win32NT 07:27:22.2 3/11/2010: Operating System Name: Windows XP 07:27:22.2 3/11/2010: Operating System Version: 5.1.2600 07:27:22.3 3/11/2010: Checking for versions of .net Framework installed 07:27:22.3 3/11/2010: .net Framework 2.0 Installed 07:27:22.3 3/11/2010: Intel® Pentium® 4 CPU 2.20GHz, 1534MB 07:27:22.3 3/11/2010: 2.19Ghz 07:27:22.3 3/11/2010: Running Randomize() 07:27:22.5 3/11/2010: Loading PlugIns 07:27:22.5 3/11/2010: Checking for applications to Launch On Startup 07:27:22.5 3/11/2010: Running Misc startup tasks 07:27:22.5 3/11/2010: Setting Menu types 07:27:22.6 3/11/2010: Opening Configuration File 07:27:22.6 3/11/2010: Getting Configuration Values 07:27:22.6 3/11/2010: Using Theme: Default - Default - New 07:27:22.6 3/11/2010: Checking for alternate Image Directory for Theme: Default - Default - New 07:27:22.6 3/11/2010: Launching HideOS.exe 07:27:22.6 3/11/2010: Initialising Video/MNG DLL's 07:27:22.6 3/11/2010: GameEx will check for media insertion (may affect performance) 07:27:22.6 3/11/2010: Hiding Taskbar 07:27:22.9 3/11/2010: Is Media Center running? 07:27:22.9 3/11/2010: Checking/Creating LCD Registry values 07:27:22.9 3/11/2010: Check Media Center Exit/Start Mode 07:27:22.9 3/11/2010: Media Center Mode 2 07:27:22.9 3/11/2010: Video previews on.
