The layout file requested by the document, scrartcl.layout, is not usable. This is probably because a latex class or style file required by it is not is not available. See the customization documentation for more information. Lyx will not be able to produce output. If I look at the source of the file it does list scrartcl. I thought this might be something with SQL-Ledger but ultimately found that the scrartcl.layout is included with Lyx not with SQL-Ledger. I'm not so much worried about viewing/editing the file now as I am about being able to assist users in editing these files if I opt to use them.
Does SQL-Ledger use the LaTeX scrartcl class? It would seem so. If yes, then you have to have that class installed in your LaTeX distro, and the message from LyX suggests that you don't. LyX flags layouts as unusable if the corresponding LaTeX class is not installed. Run 'kpsewhich scrartcl.cls' in a command shell to see if you've got it. If not, install it, update your LaTeX file name database, then reconfigure and restart LyX.
