I use Lyx quite extensively to write most of my letters.
Reason is I use LaTeX in my work so it is a nice compliment.
However, I found that the last two versions of Lyx could not process any
of my older lyx files.
The error I get was that something needs to be inserted.
DVI files could obviously not be compiled.
When I uninstalled the newer version and found an older version to
install i could open the file again as normal.
In particular, the Tables of the older version could not be processed by
the newer version.
My problem is that I have hundreds of Letters that I cannot open anymore
as the new versions object compiling them.
If there is something simple you know of how to fix this, let me know,
otherwise I will create a more detailed report.
