ok, the file is much too larger for Email David. The limit is 10 - 25MB depending on your provider.
This is the cause fir the error and could have very well initiated this problem.
If you need to send such a large file, you need to use a file sharing website. I recommend http://ge.tt
Once it is uploaded, it will provide you a link at the top. You then just email this link to the person and they download the file from the site, but emailing is not possible.
I have though, marked this question to never close, so if you continue to have any problems, you can return anytime.
But trying to email such a file (more then 30 times the limit) is why you had this problem, and the commands I had you do will have cleared this.
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
