Hi there! I see you're having trouble with the JustPlay app not loading. Let's work together to get this sorted out. Can you tell me a bit more about what happens when you try to open the app? For example, does it freeze, show an error message, or just stay on a blank screen?

Meanwhile, here are some initial steps we can try to get your JustPlay app working on your Windows device with WebKit:

1. Restart Your Device: Sometimes simply restarting your computer clears out temporary glitches.

2. Clear the Browser Cache and Cookies: Since you mentioned WebKit browser, clearing cache may help:
- In your browser settings, find the option to clear browsing data.
- Clear the cached images and files and cookies.
- Restart the browser and try loading JustPlay again.

3. Check for Updates: Make sure your browser and operating system are up to date. Outdated browsers can cause compatibility issues.

4. Try Incognito/Private Mode: Open a new private browsing window and access JustPlay—this disables extensions and stored data that might interfere.

5. Disable Browser Extensions: Some extensions could block content; temporarily disable them and reload the app.

If you have already tried any of these, please let me know which ones, so we can move to the next troubleshooting steps.

If the app still won't load, we can check for server issues or do an account verification next. Also, do you have access to your JustPlay User ID or account login details?

Looking forward to your reply so we can fix this!
