Hello Walter,
We cannot offer remote logon support, and we cannot accept your files at this time.
It is likely that you have installed and enabled Comodo Sandbox, which in turn probably prevents the self-decrypting AxCrypt files from working. Please disable the sandbox for the self-decrypting file, since they are seen as executables by Windows and Comodo. For more information check out comodo: http://help.comodo.com/topic-72-1-451-4768-.html .
It seems the Comodo Sandbox causes the green border around your window.
