I get the same thing..  White screen - Have to kill it..

When I run the CLI I get a 403 error.. Over & over...

java.io.IOException: Server returned HTTP response code: 403 for URL: https://cex.io/api/balance/
        at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)

Exception in thread "Thread-0" java.util.NoSuchElementException: No line found
        at java.util.Scanner.nextLine(Unknown Source)

Looks like something may have changed in the API?
