confused how to treat the xml files

[biffo 0]

Although really inexperienced I have had simconnect working but for some reason it failed. I have followed all the reinstall procedures and now want to make sure after, that hard work, that I get it right when I enter the inputs for the client and the server PC.

Can someone tell me the xml file created on the sever which with the client sim cfg. ~ sets the connect to  FSX.  I add any programmes like rex or sky do I add their xml details to the existing initial xm document l or do I replace the initial set up notepad document. Or instead do I have a list underneath the original simconnect xml ie., one for every programme to connected to the fsx server. Mant thanks for any replies it may be stupid I altogether have spent over a month on this,it has been like a chess challange
