Detecting language please wait for.......
The translator sent me the .sdlxliff data.
I tried to import the file but the Import failed an the following notification shows up:
Thanks for your help
Clearly something where you should log a support case at https://gateway.sdl.com/. Support will ask for the project file and the SDLXLIFF file to reproduce the issue.
Try to open in SDL TRADOS STUDIO.
If it opens make sure no Segment is set as "Locked" and if so change it to "Unlocked"
Try to import again.
