I have Zimbra desktop installed for some time now (7.0.1) and it was working fine. Since the start of the week i get "invallid Address" when i send email.

And today Zimbra desktop won't even start. When i open the programm, a black screen with a rotating circle (loading?) appears. After a wile i get an error: busy script, and still nothing happens.

Is there a solution for this problem?

Thanks in advance
