problem with converting to latex

[KostasKoudas]

I 'm trying to convert a greek document (with mathematics symbols) to latex with writer2latex.

As you can see I have installed writer2latex.

Also JRE is OK.

But, when I choose to export, a error notice appears:

save of the document βασικά γεωμετρικά σχήματα (π):

general error

general error import/export

How can I fix it?

Thank’s for your time!

I’m not sure how much help we can give with a third-party extension, although someone might know! Meanwhile, it might be worth contacting the author with bug-report or request for help.

An alternative would be to try Pandoc which also should be able to perform this conversion for you.
