I cannot send emails in outlook express without getting a blank error message. I have to go into the sent email folder to send the email and then delete it or it will continue to send the same email to the recipient. I have tried several times to attach the files that you have requested but apparently have not been doing something right. I will try once again and then just give up! I get keep getting "Uploaded file is not valid" I don't know what else to do. This is very frustrating!
