Most recent updates crashed NIS

I am told by escelated NIS support that engineering is aware of that a recent update to NIS 2014 has caused NIS to crash on some PCs. Three different support techs (including someone from senior support) uninstalled and reinstalled NIS on my PC (including going back a version) but after running live update NIS crashes again, and then while crashed it prevents access to the internet (via Firefox, Internet Explorer, and Google Chrome).
.
I was told that a patch is forth coming (may have already been released for all I know) but since NIS won't run long enough for Live update to complete how can I ever hope to have the patch installed?.
