Hi, Our program met with a compatible problem with KB944533 Any one meet with the same problem. Here is the report from our users. Comments: I submitted an error to the support folks about Ewisoft crashing on startup. I finally concluded it is due to Windows update for Internet explorer KB944533. Hope this helps. I unintalled that update and now Ewisoft works again. Thank you a lot, -- Best regards, Kelvin Gan
