[thomasp66952452]

I AM ON WINDOWS 10, I HAVE TRIED DELETING AND REINSTALLING "ADOBE DIGITAL EDITIONS 4.5" AND STILL GET SAME ERROR THAT LOCKS UP ENTIRE COMPUTER AND REQUIRE TASK MANAGER TO GET OUT OF.  HELP

I get the same error message on an iMac. My Digital Editions is 2.0 and I have not opened it for several months.
