Hello Jose, I cannot open an old format file anymore:
Traceback (most recent call last): File "d:/devel/lyx/trunk/lib/lyx2lyx/lyx2lyx", line 21, in ? import LyX File "d:\devel\lyx\trunk\lib\lyx2lyx\LyX.py", line 28, in ? import lyx2lyx_version ImportError: No module named lyx2lyx_version This is with a CMake build, so maybe this explains that. Peter, any clue? Abdel.
