I just started using lyx two week ago and I'm using a version 1.5.1. Somehow I lost all the document class so that for every writing I created the lyx said layout file was required and it could produce any output. Maybe it's because I updated the MikTex?? The same problem happened before and I just reinstalled the lyx the last time.
A second question sounds very stupid but I have no other choices but asking. How can I update the lyx 1.5.1 to 1.5.2? I downloaded the patch but don't know how to do next. It says "This patch should be applied like this cd lyx-1.5.1 make distclean zcat patch-1.5.2.gz | patch -p1 and then LyX can be build as usual." but I have no idea about what this is talking about. By the way I'm using windows...... Please help me out. Thanks very much!
