I went to the Maya Riviera a couple of weeks ago. My wife and I had new Aeris atmos 2 computers. I Had a total of 6 actual dives, 2 other dives [that were just cooling down after suiting up in 90+F in the jungle for a couple of cenote dives.] for a total of 8 dives. My wife had also 6 actual dives plus 2 cool downs. When we got back to the states I tryed the Universal Downloader Software and began to download the dives to my computer. Strange thing was that the software only saw and downloaded the last 5 of the dives from both of our dive computers, leaving off the first 3 dives. The really strange thing was one of the dives it could not download showed that the size was over 32000 bytes. The dives it was able to download were about 500 bytes. The dive I had on my computer that was 32000 bytes was actually a duplicate of a good dive that was downloaded. The software did not even show the first 3 dives in our computers. I called support at Aeris which I was directed to support at Oceanic seems they are sister companies [Thats why the Versa Pro looks so much like the Atmos 2]. I downloaded a patch which upgraded the software. The patch fixed a temperature readout on the divelogs but not this specific problem I had. I told support about this and they said it was suppose to fix this problem too. Funny thing was the text note for the fix only mentioned the temperature fix. I think my leg is being pulled abit here. Anywhey support tells me to send back both computers and the serial com port connecter cable because they think that the problem is either our coputers or the cable. It does not seem likely to me that it could be the computers, I could see one of them malfuctioning but both have basicly the same problem [I don't think so]. If the cable was bad I don't think it would see anything at all. I'm not a support Tech but I do know computers pretty well and it sounds like they are just copping out on this issue. I don't want to go through the hassle of shipping everything back and not having anything solved. Sure I might have new computers sent to me but what happens when I go on another trip and do 6 or 8 more dives and the software leaves the first 3 dives off again. I believe when I pay $160 bucks for software it should do what its suppose to do. Has anyone out there had the same problem I have. I spent 3 days trying everything I could think of to solve this problem. You're imput or if anybody figured out how to fix thiswould be appreciated.
