GedSite supports GEDCOM files exported from GenoPro when using GenoPro's File > Export > Export to GEDCOM via the Report Generator... command. This is the recommended method for creating GEDCOM files from GenoPro for use with GedSite.
Do not use GenoPro's File > Export > Export to GEDCOM Format... command with GedSite. It does not produce a valid GEDCOM file. It includes many custom records which are valid but unused in GedSite. More importantly, it does not use standard GEDCOM records for marriages and other important data; that data is specified using invalid GEDCOM constructs. GedSite has rules for processing some of the invalid and/or non-standard GEDCOM records, but the results will not be as good as when using the File > Export > Export to GEDCOM via the Report Generator... command.
