Check the tournament rules. It is likely that you live in a state that does not permit skilled gaming... therefore no Ready-Gos are available to you.
"To participate in a Tournament, you must be a resident of (a) the United States but excluding residents of: Arizona, Arkansas, Connecticut, Delaware, Florida, Iowa, Illinois, Louisiana, Maryland, Montana, South Carolina, South Dakota, Tennessee, or Vermont, or be subject to the laws of one of those states (b) any other jurisdiction that WGT excludes in its sole discretion. Residents of Brazil, Argentina, the People's Republic of China, South Korea, and Japan are also excluded"
That search box on the right works great, I found this in about a minute.
