Thanks Mario!
The error information helped me figure out the solution.
It said the password did not match. I have a different password for my database and my FTP. When I set them to the same password, it worked.
Not exactly sure what happened here, since my FTP username is different, and having a file on the server shouldn't require the FTP password. But it worked out anyway.
Thanks again for making such a fabulous software!
