I would like to say that there is no need to double post. Most of us do see it on either a regular, or semi-regular basis. Also, as a suggestion, have you tried downloading it other ways such as the torrent provided by STO, or if you're direct downloading from the STO website, try the Steam download, if you have it. In addition, if memory serves right, I do believe that not many email providers allow attachments over 5mb, from what I've seen. But I could be wrong.
I sed to have patch client error when i first installed STO. All i idi is right click on the icon and "Run as Administrator" - the patching should proceed and then when finished patching ...click Engage.
