Problem authenticating

I am running an admittedly much older version of SEOTools; when I authenticate, which I am assuming must have been happening using a Windows ActiveX browser control, as of today I get the attached message
(screenshot attached) - "This browser is no longer supported" OK, I'm running IE10 on my machine - I upgraded to IE11 - same message.
Should I upgrade to a newer version of SEOTools, or is there some trick to getting this to work?
Any advice appreciated! I really rely on this tool for some monthly reports I've developed! Thanks - Ted

You need to upgrade to the latest version of SeoTools.
