The latest version 2.0 fails for import survey structure with this error message "Import failed. You specified an invalid file type 'xml'."
I have tested it to make sure it wasn't my fault, so I created a simple dummy survey, export it and import it back, it keeps rejecting it, no matter I download and upload the .lss or .xml files in unix, PC, linux or Mac text file format, so it can't be caused by the file formatting problem.
I looked at the .lss and .xml, both files look perfectly ok.
I have no problem with importing the survey structure with older version 1.9
