You are the one asking for help. The problem description was insufficient,
so Gary requested further information by asking you to "right-click on your
error message, copy, then paste it into a reply here". Gary has provided
those instructions many times in the past, probably hundreds of times. Most
people do not have a problem complying.
You won't get help until you supply more specific information. It is not
because people are being difficult, it is because there is not sufficient
information. You are causing people to spend time asking for clarification
instead of providing something useful for you.
People that sincerely want to help sometimes get frustrated with people that
ask vague questions, and when they ignore requests for additional
information, it can be very frustrating. The best response is to not take it
personally but do make more of an effort to help others help you.
