From time to time my 9210 loses the ability to save and open M$ .DOC word files. Then I hassle around, reload several things like all memory card data and all 9210 data, viewers, word etc., and generally I manage to restore the functionality.
This time I cannot, instead.
Where the hell are the converters for .doc files for the word app? Thanks

... answering to myself... :D

Uninstall Word, and uninstall something that, in English, should be called "Converters for Office 2.0", 26 kbytes large.
Then restart, and reinstall Word from Word.sis.
Look at the list of installed apps, and converters for office 2.0 should be there again.
Done.
