I'm an HOF subscriber, but can't access the DFS Lineup Optimizer.

Some of the most common explanations: 

1. It may be too early in the preseason. Our DFS tools are available one week before the start of the regular season. 
2. Make sure you're logged in to the correct account. 
3. If you're logged into the correct account, try logging out then logging back in. Sometimes it takes a little while for our system to fully update your premium status across all tools. 

If none of these explanations work or apply to you, then submit a request and we'd be happy to help you further.
