Version 5: Patches are available on-
Version 5 DVD Mac users upgrading to Yosemite: Unless you “check for updates” and apply these before upgrading to Yosemite, you may find your previously working Wordshark 5 or Numbershark 5 DVD returns an “Error Code 16”. Installing our DVD releases 5.01 and 5.02 onto Yosemite “from new” will also return this error. We have patches for this issue here
We expect to have 5.03 DVDs available that have this additional coding built in by the end of 2014, and UK customers who do not wish to patch may exchange their earlier DVD releases for the nominal “damaged disk” charge from Jan 2015.
