Use the "General" data type as you create your MaxDiff Analyzer project. This is a .CSV file (comma-separated data file) where respondent ID must be in the first column. You should keep the ratings on the 5-point or the 10-point scale...however you collected the data. (Don't convert to 1/0 unless it was pick-any data from a multi-select grid.)
I'd use the Threshold method of reach, where you can adjust what the threshold should be. For example, if you think that either a 4 or 5 on a 5-point scale indicates reach, then you set the threshold at a "4".
Weighted by probability requires that the data are on the logit scale, coming from a MaxDiff experiment and if data estimation was individual-level MNL, such as HB MNL estimation.
