I have owned a suunto vyper for three years. I have used the dive manager 1 for two of those years and dive manager 2 for about a year and a half. Recently coming back from a trip to Cozumel I went to down load the dives and nothing occured. It will download the first 64 dives in the computer but not the last 6. I tried another computer and a new down load cable but again nothing happened. It still only download the first 64. Can anyone shed light on this problem or has anyone had this occur with theirs?
