Hi there! I understand the FoE Helper app’s calculator pops up but won’t fully open for you. That sounds inconvenient. To get started, could you tell me:
- Did this issue start happening recently after an update or change?
- Have you tried refreshing the Forge of Empires game tab or restarting your browser?
- Are you using the FoE Helper as a browser extension or a standalone app?

Meanwhile, let's try a few simple steps:

1. Refresh the Game Tab: Sometimes, FoE Helper needs the game page to reload to work properly. Just refresh the browser tab where Forge of Empires is running.

2. Restart Your Browser: Close all browser windows completely and then reopen it. This can clear temporary glitches.

3. Check For Extension Updates: If you’re using FoE Helper as a browser extension, ensure it’s updated to the latest version. You can usually do this through your browser’s extensions page.

4. Clear Browser Cache: Sometimes cached files can interfere. Clear your browser’s cache and cookies and try again.

If those don’t get the calculator working, next we can look into more technical fixes like checking browser permissions for pop-ups or possibly reinstalling the FoE Helper.

Could you try those and let me know what happens or if you’ve already tried any of these? That way, I can help you further!
