Good on ya, sorry i couldn't be more help. I don't see what you did wrong by asking that question.
I wish more members would;
"Either share your wisdom, ask legitimate questions or please stay silent."
People who are members here for a longer time have noticed a considerable rise in end-users/pizza techs. The general consensus has been to confront them early on or it results in more heartache further down the line.
10 hours on a driver problem is excessive and would not be something you would expect from a normal tech!
