Paul was fantastic Paul was fantastic. I have been chatting with several other people since April 3 and no one could figure this problem out. I was emailed that this issue had been referred to technical support and they could not provide adequate assistance. As I am not computer friendly, Paul was very helpful. He was very patient with me. I am extremely grateful to him for resolving this issue.
