	4. Troubleshooting
----------------------------------------------------------------------------
1. For ComMotion Transmission Server, check the License Wizard in ComMotion

   TRanmisssion Server will stop working with your boards after 3 weeks unless
   boards are upgraded with License Wizard.

2.Common tips:
	ERRLOOK.EXE is very useful utility to translate error ID to text format
	(is provided with Visual Studio)

3.VBClient/Custom application does not connect to Server:
	Ensure that you are providing correct Server address (in IP,DNS,UNC form).
	Ensure DCOM is enabled on this computer (dcomcnfg.exe,
	Default properties tab)

4.VBClient does not run:
	You might have old version of OLE automation DLLs. Run VBRUN60.EXE to 
        autoamatically set up OLE automation DLLs.

5.Setup failed:
	Restart your computer and run setup again

6.Transmission Server hangs:
	Exit it by running Kill utility provided in the main 
	ComMotion Pro folder. Use Run in Window's Start menu 
	(i.e. - "ComMotion Pro directory\Kill.exe TrSrvc.exe").
	You can also stop TransmitterService from Control Panel Services Icon.

7.Transmission Server stops working with message that buffers overflow:
	Make sure that you have set the correct (existing) IP address in case of unicast.
	Make sure that you have set correct bit-rates.
