I have encountered similar problems. In most cases, I have not been able to open the files under any circumstances. The first time I encountered it, a GEDCOM program was sent to me by a friend who was running under Windows95. I was running under 3.01 at the time. I had to take the disk to work, have a guy copy the disk from W95 to DOS then back to W3.01. Finally worked, but the process is to complex to do everytime. Good luck. Larry
