I have recently upgraded my LyX installation form 2.0.7 to 2.1. Everything was fine until I found out that I am no longer able to open my older Beamer presentations made with LyX 2.0.6 or 2.0.7.
Whenever I try to open my older Beamer presentations in LyX 2.1 , it shows an error like this:
/tmp/lyx_tmpdir.ThevfvKK5936/Buffer_convertLyXFormatXXXXXX.lyx.YoiTshcj5936 ended unexpectedly, which means that it is probably corrupted.
I am having the same problem on both Win 7 SP1 x64 and Ubuntu 14.04 x86-64.
Initially I thought my files were corrupt. To make sure, I tried opening all of my older Beamer files. And every single time LyX showed the same error.
Any help would be much appreciated.
