Two options: 1) download latest cryodex (3.8) and new export option will be there. Save the jar file in the same place as the old cryodex jar file. When you do the juggler export, it will create a file XWingTournent.json in the same folder as the the jar file. Use that for juggler.
2) try to import using the html file. In cryodex, do a export tournament report. This will pop open the html file in a web browser. Do a file-save as and save thr web page someplace convenient. From juggler, use that file in the import from cryodex option when creating the tourney.
The second option is probably easiest, but you might get some problems - the html file was meant for human consumption, and easily breaks the parser I wrote for it. The Json file should always work cleanly.
Hth !
