Hi there! I understand you're having trouble logging into the Houston Rockets app with your new account to access your tickets. Let's work through this together.

First, can you tell me what happens when you try to log in? For example:
- Do you get an error message? If yes, what does it say?
- Are you certain you're using the correct email and password linked to your ticket purchase?
- Have you tried resetting your password just to be sure?

Meanwhile, here’s a step-by-step approach that usually helps new account login issues:

1. Confirm Email and Password: Make sure you are entering the same email you used to buy the Rockets tickets. The app syncs tickets to your account based on that1.

2. Reset Password: If you're not sure about the password or it's not working, try the 'Forgot Password' option in the login screen to reset it.

3. App Reinstallation: Sometimes, uninstalling and reinstalling the Rockets app can clear out any glitches. After reinstalling, log in again with your verified credentials2.

4. Clear Browser/App Cache: Since you're using Windows with a WebKit-based app, sometimes cached data can interfere. Clearing cache or running the app in a fresh browser profile might help.

5. Login via AXS Website: The Rockets use AXS for ticketing. Try logging into your account directly on the AXS website using the same email and password to see if your tickets appear there.

If you can share any error messages or what you've already tried, I can give you more targeted help! Does any of the above sound like something you haven’t tried yet?
