Buying serial number for DivX 6.2.2

I'd like to buy a license & serial number for Divx Converter 6.2.2 but can't find any information on how to do that. I have the trial version downloaded on the computer but it's only a 15 day trial. Will the license for the DivX pro (v8) from the checkout page (the only version I see) work for the Divx 6.2.2 converter?

Thank you--I know this is not a technical question but having a helluva time finding answer to this question.
