mysqldump: Error 2020, HOST won't help..

[FightRice.com]

I'm getting that error and you can probably guess what table is giving it to me, stupid attachments.

Anyway, i contacted my host who told me to contact IT, who in turn told me to contact someone else, I'm on a shared server right now, which is fine for my loads and all, but i can't back up my databases now because of this.

Is there anyway to exclude that one table while i am backing up with SSH and then back up that table later,

The only way i can think of is to use phpMyadmin but i don't like doing it that way, and it'd be like 6 files to do it anyhow which would be a PITA. Thanks
