Well, here we go. Your other tool knows exactly 2 types of questions. One is defined by inputting "FreeAnswer", so if there is no FreeAnswer written, it needs to be the other one.
However, have a look on Limesurvey. There are sooo many more question types and options, it is basically impossible for a tool to "guess" what kind of question type you actually want.
I don't know, but you probably could write the LSS files in an external XML editor, but this is for sure a little mor complicated than what you had to do with your other tool. But this is natural, as Limesurvey has so many more options.
