1. When the plane loads the first time the v-one gauge shows and can be called via the icons. When I press Crtl+Shift+R to reload it to get cockpit sounds safeties,altimeter, lights' clicks etc.. it seems to crash and freeze everytime I touch a key I get the ding.dong and the only way to exit the sim is via Task manager,that I know of?
2. Can't say because it doesn't load that far... So the sounds can be heard?
3.In FSX/Gauges Folder
4. Under FSX\Sound folder in a folder "Callouts" ( I added the callout from your post # 53 They work, but I don't know,am sure? Exactly how to add the v-one? Since the way I have added it via intruction, gives me the issue...Ding-Dong and freeze  :-[ NOw I messed it up. Trying to install the v-one gauge again, by adding the XML lines at the bottom below the alt_calls and renumbering the gauges all has gone quite, even after Ctrl+Shift+R Stragely it loads Without the ding-dong or Freeze...But without cockpit sounds Here is my section of the VC01 section...I removed the entries to the V-one and only kept those for altcalls and the sound still don sound  :'(
