Johan: Thanks for your reply, But I have not reinstalled FSX at all. All I did was to uninstall 727 2.3 to put in 2.2 as 2.3 is so full of issues and edits that I couldn't handle....And then this happened. I went into the KB to study the matter and it says in there that this happens when to protect the software;
Despite my resintalls and my legal copy I can't get the gauges or pop-up panles to display. Even in my last reinstall I disable UAC and that didn't help either  :'( Just checked the panle folder for CS727-100 in there there a whole lot of CAB files Captainsim_721 P1,P6 etc,A gauge file and a Panel.cfg at the bottom I also own 727-200 skin with the 737-300 panel in there the panel is called: Panel.a727 and in it there ia a panel.cfg; a CAB file:csb727 tools.CAB and cs.a727animation.gau.
Yousay:Also try to copy all your gauges to the general gauges folder of FSX. But all is packed in these .CAB files. I completely lost. I've even done,according to the KB deleted the captainsim folder from the registry and after reinstall. But I get the same result No engine gauges or pop-ups???
