Sending by email takes hours

[DTeicheiraMD]

Express dictate has been working very well for me for 6 months. However, two days ago, after a successful send in the morning, every other transcription that I try to send takes HOURS to process and send. No changes have been made. For instance, 3 hours ago I hit the send button, and I got the typical "do you want to send this dictation?" I hit yes and at the botton the processing line says something like 19%. Hours later I get the email prompt, and hours later it goes through outlook express. I tried stopping the "Use the automatic gain control", I changed the compression options, changed to smpt and it doesn't make a difference. What can I do to get it to work like it used to?
