I have a problem with sound on AN124 and AN225. When I select either acft. before it loads a "sound file not found" error message pops up.  I have to click ok 4 times to load acft.  once it is displayed sound is perfect. changing views (spot to cockpit for example) the error pops up again. clicking ok allows completes the change. Also if I exit FS2004 with either acft. I get the error message that FS encountered an error and must close and asks If I want to send to MS. I have temporarily replaced sound file from another heavy which has no problem but still get same error message. I'm lost
