Yes, you can import translations that have already been done in Transit Satellite PE. The file that contains the translations must have the .pxf format. In order to check its format, right-click its icon, select Properties and click the General tab. You will find the file format next to Type of file. If it is not a .pxf file, you can't import it in Transit Satellite PE. For further information, I suggest you contact the developers using the contact information from the official web page.
