I have the same problem. I have a wordpress.com blog and a www.remarpro.com blog.
I have an api key for the wordpress.com blog.
All the ‘help info’ says that you are supposed to use the same key.
I don’t know why this SHOULD work when the passwords etc. are different, so how could this possibly be the CORRECT answer.
Well, OBVIOUSLY it isn’t because I get an error code.
CAN ANYONE OUT THERE ANSWER THIS??? I would really like to post a video on my blog but can’t without the correct API key.
Super frustrated.
