So, I went and updated my MikTeX packages (the only ones that needed updating were authordate, floatflt, pdfpages, cm, caption, and babel) and also installed the ifxetex package, and the problem went away. I don't think any of the packages but ifxetex have anything to do with pdflscape. Why in the world does a Windows installation of MikTeX and LyX care about Xetex -- a Mac TeX system??
XeTeX is not a MAC system. It is a Unicode variant of LaTeX and the new thing in MiKTeX 2.7. So perhaps one of the LaTeX-packages you load in your preamble use now XeTeX when it is available. As it is now available in MiKTeX, it is tried to use it.
