I use a freeware sound file for RR Sey engines on a couple of aircraft and I find that when I load these aircraft I get a screen error message'sound file not found' at the beginning of the load process which causes problems loading. When I eventually get the aircraft loaded and fly it,the sound is okay and as it should be.So what is causing the error message?:*

It has nothing to do with the sounds. It's the panel. One of the gauges is using a sound file that's missing from the FS2002 sound folder...try a reinstall of the panel.-E

Thanks Erick,I'll try that.
