[GeoNetwork-users] Geonetwork deleting profiles and data

Hi Everyone,

I have been working with geonetwork for a little while now. I have made minor changes to the appearance of the page, but other than that, no serious messing with the code. I have also loaded numerous xml documents into the embedded database. ( I am using the jetty/mckoi configuration on windows XP)
I have modified the admin acct to my own username and password, and also created other accts for reviewers and editors. Now, out of the blue, several times now, when I try to log on to GN, my password is no longer recognized and all my data is gone. does anyone know of why this might be happening? I have not been in GAST, I have not reformatted my database, yet the acct's all dissappear except for admin/admin. The first time it happpened, I uninstalled and re-installed the software, and everything was fine for about a week, but now it has happpened again for no apparent reason.

Any help would be great.

Thanks,
Cat
