Hello,
Thanks for your replies.
I use Transit NXT, Version 4, Service Pack 8.
I always perform a format check before delivery ("Prüfroutine", blue-white flag symbol in my version).
As I receive packages ready for translation from my client, I cannot convert the source text before translation, unless I ask my client to do so.
Error message says (roughly translated from French) : " the file "xxx" cannot be opened. Some problems have been detected in its content".

Thanks for any help
Jérôme
