hello,

what i am trying to do is:
1.opening a .doc-file in OpenOffice
2.saving the file as .odt-file
3.exporting file to .tex-file
4.importing .tex-file to lyx
   then the message:" .. file is from a different lyx-version, but 
lyx2lyx couldnt convert it .." appears

i am using OpenOffice 2.3.1 with writertolatex 0.5 and Lyx 1.5.3
