Great ! So that was the problem; the "older" converter provided by rkomar works perfectly, while the "new" converter freshly provided by the PocketBook assistance do not ! I'll let them know. Now I'm a happy man, for I can convert whatever I want. Thanks to all for the precious help. In case you are interested in some fine and pocketbook-ready French dictionaries you can find them here
