Yes I did when first installed plug in and it brought up the settings. However I decided to check it after reading your reply a few minutes ago. I didn't realize that the characters listed in the posting key section was not the the private key and that I needed to click on the box on the right to show the private key. Once I corrected the key it worked! Thank you. Thank you. Thank you!

I'm glad that you managed to resolve the issue. No problem at all. :)
