after I downloaded the recent fix for Windows Live Mail 2012 all of my Categories (mailing groups) disappeared both in WLM and online. I recreated categories but the ones I created yesterday have already disappeared. Seems that I can create new categories but the earlier ones then disappear. In have Windows 10 on my computer. I don't want to switch to Windows Mail, as it does not seem to have capability to create Categories (Mailing Lists) in Contacts.
