Hi,
If you get to the point of seeing the message ready to send and then click on the send button, do you see an uploading message?
For an image that you have just emailed, go to the Information panel on the right hand side and look at History - does that end with an emailed message?
Most errors I have seen have occurred before the email is actually sent.
It could be a problem with the Adobe server but I have just managed to send myself an image.
The other possibility is that the email is being blocked by a spam filter somewhere.
Brian
