Hi Ingrid Fischer 

Your customer PM does not seem to be very familiar with the way Studio packages work. 
What you did was correct: send back the SDLXLIFF file. In fact, if you had sent back a return package, the PM would not have had much more because the return package does not contain anything else than the target SDLXLIFF. 
Tell the PM to simply copy the translated SDLXLIFF into the project folder on his side and she will be OK.

The error message you show is strange because it only comes up when you try to open a SDLPPX that you have created yourself, but you tell me that this package was created by the PM, not by you, so it is probably the wrong package.

What you could do - but it's cumbersome and unnecessary in this situation - is to open the SDLPPX from your customer (assuming it is the right one), unzip it into a new project folder of your choice, then copy your translated SDLXLIFF file into that project folder and then create a return package for that project. 

FYI: SDLPX and SDLRPX files are common ZIP containers. This means that if you make a copy of such a file and change its file extension to ZIP, you can easily see what is inside the package.

Thank you again Walter

You are right: at the end, she simply took my .xliff file and could work with it.

So the issue isn't that urgent anymore, but I still tried your method in case this happens again in the future.

The SDLPPX-file unfolded into a regular SDLPROJ folder with the complete usual architecture. I copied my XLLIFF into the "French" folder, replacing the empty one. But I still could not create a return package : same message :/

Luckily I know now that the XLIFF file works just fine too

Thank you!
