Page not found (error 404) / Also Blog instead of Website

I actually have two issues.

1. I confirmed my email address, and went to sign in, but after I enter my information to log in, instead of the dashboard, I get this error message: Page not found (error 404)

2. I intended to choose website hosting, but it looks like I accidentally selected blog. How can I change that to hosting?

Thanks in advance!

Follow up: The issues have been resolved, so I no longer need support.

For anyone that may benefit from the following, if you accidentally signed up for the blog, but wanted hosting instead:

Log into your account. Under Settings > Convert to AlterSite > Follow what it says and confirm.
