First thanks to the poster who used the Olympus FE 340 screen protector, I ordered two from Zagg and put one one and dove it the next day. The 'OEM' screen protectors started bubbling and peeling after 1 dive, the Zagg was as I put it on after I did two dives to 80' in saltwater. The down load and upgrade went fairly smoothly. I can see where someone COULD get confused and try to upgrade the DC with the compressed file - maybe a slight name change from compressed to uncompressed? My buddy 'bricked' his and altho he didn't believe my advice that i gave him thanks to Ron R's post and had to call Atomic, he got it straightened out. A slight glitch in the installation of the Cobalt Dive Log. Altho the install gives you the option to put the install in any folder, it won't run unless it is in the C: drive (the default location). Also when I downloaded new dives to the Log Book after I had already downloaded dives initially to the log book, it downloaded ALL the dives, old and new, so I had to send most to the recycle bin in order to add the 4 new dives. Is there a work around for this, seems like a waste of time and 'bandwidth' to do it that way. Many thanks to Ron R for keeping us up to date on everything as frustrated as some of the posters got!
