I've purchased IncrediMail Plus but it just won't work. I can't send and receive any mail. When trying to send a message it disappears as it was sent but nothing even shows up in Sent items. I've disabled the Firewall but it doesn't help. Sony Vaio laptop OS - 64bit win 7 Processor - inter core i7 276QM RAM - 8 GB Any ideas what's wrong? Thanks.
