Hi Shashie
A quote from Obsessed2 in another post: "When I was in the U.S. Navy we had 10 Commandments of Damage Control. One of them I like to use often is: Stay calm, don't give up the ship."
I am no more technical than you are, so I can't help much. It sounds as if you have combed the forum for answers, which is an excellent first step.
I think I'll let the gurus answer your other questions. The biggest difficulty I see for you is if you can't turn your PE completely off. Or does the reset end with it off? I forget.
Good luck, you'll get it!
