I hope this helps some one out. I just spent a long time figuring this out. I misunderstood the instructions and other tips found here. I read them that you need to change all "." to "_".
First off, call your host, I can't stress that enough. If they will, have them dictate exactly what you need to enter.
What hung me up was I thought I needed to turn all "." ti "_". But I only had to turn the ones for the db_name. The user name and sql host used "."
Also my sql database host was different than my regular host.
