Of course I don't have the individual journals, but I have last working backups as of January 20th 2008. I could pack those up, together with LJ-Archive (as a reader) and put them online.
You would have to put the .net framework on your computer, or otherwise make it work on a Vista crate (shudder) where, AFAIK, .net is part of the package. I can't help you with that. But backups do exist if GJ goes away forever.-
