Hello, Although I've always had GameEx installed in my arcade, a couple months ago I decided to donate the money and receive the full version. It's been working wonderfully since then. However, recently after updating to the latest version, I launch GameEx and the "GameEx is now Loading" screen pops up and then it quits with the error window saying "Error: Not A Valid Bookmark." amongst other things. Oh, and I havent changed ANY settings on GameEx for a while now and messing with the options is probably not the cause. I have looked for someone having the same problem but I have found no one. Please reply if you have any information regarding this error. Here's the complete error code: 03:12:26.4 8/14/2009: Operating System Platform: Win32NT 03:12:26.4 8/14/2009: Operating System Name: Windows Vista 03:12:26.4 8/14/2009: Operating System Version: 6.0.6000 03:12:28.0 8/14/2009: Vista Aero running 03:12:28.0 8/14/2009: Initializing Vista volume control 03:12:28.0 8/14/2009: Checking for versions of .net Framework installed 03:12:28.0 8/14/2009: .net Framework 2.0 Installed 03:12:28.0 8/14/2009: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+, 1982MB 03:12:28.0 8/14/2009: 2Ghz - 2 Cores or CPU's 03:12:29.7 8/14/2009: Running Randomize() 03:12:29.8 8/14/2009: Loading PlugIns 03:12:29.8 8/14/2009: Checking for applications to Launch On Startup 03:12:31.3 8/14/2009: Running Misc startup tasks 03:12:32.9 8/14/2009: Setting Menu types 03:12:33.0 8/14/2009: Opening Configuration File 03:12:33.0 8/14/2009: Getting Configuration Values 03:12:33.1 8/14/2009: Using Theme: Default - Media Center 03:12:33.1 8/14/2009: Checking for alternate Image Directory for Theme: Default - Media Center 03:12:33.1 8/14/2009: Using Images from theme: Default - Media Center V1\MEDIA\ 03:12:33.2 8/14/2009: Launching HideOS.exe 03:12:33.5 8/14/2009: Initialising Video/MNG DLL's 03:12:33.6 8/14/2009: GameEx will check for media insertion (may affect performance) 03:12:33.8 8/14/2009: Hiding Taskbar 03:12:33.9 8/14/2009: Is Media Center running? 03:12:33.9 8/14/2009: Checking/Creating LCD Registry values 03:12:34.0 8/14/2009: Check Media Center Exit/Start Mode 03:12:34.0 8/14/2009: Media Center Mode 2 03:12:34.1 8/14/2009: Video previews on.
