I'm a first time user and it took me two days to get my profiles up for precisely this reason - every time I went to save up would come the dreaded "Can't find Server" window. When the server was eventually found my work, unfortunately, was not and I had to start again.
I overcame this by writing everything out in a Word document and when the Auctiva site was accessible, copied and pasted the words. Since the Auctiva servers are so unreliable I am now doing this for everything. Frustrating, time consuming ... most definately but it works.
I use web based applications at work and here at home and many have a cache on th elocal hard drive to write temp files to so they can be recovered if the internet connection fails for any reason. I'm not a techy so I don't know how it works but the technology is available and it would be useful to have it.
