I am sure the Method team is already on this - however, should someone need the work around I discovered today (after a couple of days with the Quickbooks Tech Support Team ) here is what I learned.
Problem: QBE13 (R6) was aborting instantly upon entering the password.
Workaround: When you are entering the password in QBE13 R6. Enter the password - do not hit OK yet. Press and HOLD the ALT key until the Quickbooks HOME screen appears then release. This will bypass the conflicting sequence that needs to be addressed in METHOD ( according to Quickbooks)
Hope this helps.
(all other releases are fine as far as I know)
