Dave,
This sound very concerning. Lost charts or encounters are no laughing matter as much as I did try to put a smile on your face. Have you called tech suport yet? This sounds like a job for the mothership to me. If they haven't already, they can securely upload your database and look it over for issues. How that will proceed is anyone's guess but it is certainly worth a try. Please let us know how things go and what you find out. Best of luck on all this....
Paul
