Hello cosimo de paola ,

If I understand correctly, you are translating EN-FR, and up until recently everything was fine.

Therefore I think the first thing to check, would be your Studio settings as these may have inadvertently been changed-

File-Options-Language Pairs...

The default setting is 'When no match is found- Leave target segment empty-

However if you have 'Copy source to target' enabled, this may explain the behaviour.

Hello Steven, tx for your anwer. The settings are OK.

It is a really strange thing. 

In fact, everything was fine up to a specific segment. Once that segment was over, all the segments which follow, even though translated, are not copied in the target file, EXCEPT FOR the footnotes. The footnotes are correclty copied. 

As  a workaround, I changed the initial Word file, cancelled the problematic segment, reopened it in Trados, made a simulation and the segments following the previous problematic segment were correctly copied.

But I don't have time to apply this workaround for the whole file. My file has 10,000 segments, the problem happened at the 2820th segment and I noticed the problem yesterday (so far, I have translated up to the 3850th segment). I would have to go through all the 3850 segments because I have to choose the right translation proposals... I would lose several days.

I hope to be able to use the initial Trados file.

Hello cosimo de paola ,

What happens if you first take the original file (copy it and rename it first), then open this 'new file' as a 'single file translation - then once opened in Studio- simply 'save target as' (without translating anything).

Are you able to do this? Or are there errors?

Could I also ask you when replying to add @ before the name as this ensures the recipient is informed-

As otherwise your reply can get 'lost' in all the coommunity activitiy.

Hello again, this is the operation I do the first time I receive a file, in order to check that there are no errors in the initial file. Everything was ok.

As suggested on another forum, I also tried without  translating the "wrong segment" as well as the preceding and the following segments, but it did not work either. 

I'm despaired.
