Mr. Van Quang

Did you have a tech support question for the other users here?

This isn't a live chat forum, if you were thinking that it was. You post your question, providing as much detail as you can, and then wait for one of us, who are mostly your fellow users, to see and read your question and offer suggestions. Such a reply may not arrive for a couple of hours or more depending on your question, so you'll need to be patient.

Regards.
