I am here to help you. If you need more assistance please reply back here and before we go any further, be sure to click the POSITIVE RATING now. Doing so does NOT close the question or prevent us from continuing our conversation here. My livelihood truly does depend on your positive rating.

Clicking the "bad/poor" rating does NOT issue you a refund.
