It seems to be really nice stuff but i'm unable to run it properly - with everything installed my gym 1.0 runs but won't play or do anything, displaying the unhandled error message, which i can skip but nothing happens (nothing works) I dunno whether this is going to help but here are the details: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.NullReferenceException: Object reference not set to an instance of an object. at Lister.Classes.PlayQueue.Play() at Lister.MainForm.pb_Play_Pause_MouseDown(Object sender, MouseEventArgs e) at System.Windows.Forms.Control.OnMouseDown(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) ************** Loaded Assemblies ************** mscorlib Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows.0/microsoft.net/framework/v1.1.4322/mscorlib.dll ---------------------------------------- GYM Assembly Version: 1.0.2143.22909 Win32 Version: 1.0.2143.22909 CodeBase: file:///D:/Downloads/flock/GYM1.0/GYM1.0/GYM.exe ---------------------------------------- System.Windows.Forms Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows.0/assembly/gac/system.windows.forms/1.0.5000.0__b77a5c561934e089/system.windows.forms.dll ---------------------------------------- System Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows.0/assembly/gac/system/1.0.5000.0__b77a5c561934e089/system.dll ---------------------------------------- System.Drawing Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows.0/assembly/gac/system.drawing/1.0.5000.0__b03f5f7f11d50a3a/system.drawing.dll ---------------------------------------- System.Xml Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows.0/assembly/gac/system.xml/1.0.5000.0__b77a5c561934e089/system.xml.dll ---------------------------------------- CSSound Assembly Version: 1.0.2143.22689 Win32 Version: 1.0.2143.22689 CodeBase: file:///D:/Downloads/flock/GYM1.0/GYM1.0/CSSound.DLL ---------------------------------------- ************** JIT Debugging ************** To enable just in time (JIT) debugging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled. For example: <configuration> <system.windows.forms jitDebugging="true" /> </configuration> When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the machine rather than being handled by this dialog. And versions 1.1 and 1.2 just keep popping unhandled exceptions and when i press skip it just pops up again.

Otherwise, I'm running a winxp sp2 with .net 2.0 and don't really have any problems with running any other stuff
