Thank you for the report. We are aware of an issue where the screen turns black when loading into the tower. We are testing a fix and will update via [url=http://www.twitter.com/bungiehelp]Twitter [/url]when we have more information. As a workaround you can open the map and activate the Tower Landing Zone to reload the tower. You may need to try this multiple times to correctly load into the tower. Hope this helps!
