GoDaddy 1 Hosting 2 Domains 2 WordPress

I’m sure this topic is beaten with a dead horse but please help me!

I have championshipphylon.com up and running with wordpress, no sweat!

I upgraded my economy hosting to deluxe, a couple days ago, so I could host my other domain, imisstheoldacg.com, on the same hosting plan along with championshipphylon.com with another wordpress

I’ve installed wordpress under imisstheoldacg.com/blog, since it would not let me host it under the root directory, I’m thinking because there is already one installed there for championshipphylon?

Sooo…..

1) Any reason why the wordpress is not showing up under imisstheoldacg.com/blog even though GoDaddy is showing it installed? “This website is temporarily unavailable, please try again later.”

Also…

2) Once I get that up and running, I really need anyone who is going to go to imisstheoldacg.com to be automatically forwarded to imisstheoldacg.com/blog, how can I do this?

Please help! Thank you.
