Symptoms: You get a return package (*.sdlrpx) from a translator to whom you sent an project package (*.sdlppx) but you get an error message saying you can’t import the package.

The file will look like this: 
Just double click the file and it will open in Studio and will be added again to your projects list. See how to open a project.
After that just try to open the return package again, and it should get imported just fine.
