If you attempt to launch Amira and see a blank screen or "clouds" screen that looks like this, there are several troubleshooting steps you can take.

1. Check that firewall and content filter requirements have been met
Firewalls, Content Filters, Proxy Servers, and Virus Protection can impact Amira’s overall performance significantly, even in cases where bandwidth appears sufficient.
