It was a good idea to contact the CO, wasn't it?
It will be resolved soon mate don't worry about it, just send him that police check again by e-mail. No problems at all, but let him know that you have already uploaded it on the system the first time when you applied.
I think there is an error with my application as well, I applied on 14/09/2013 and haven't got the damn Bridging visa grant e-mail mate, which hasn't happened to anybody. Don't know what is going on. Everybody got it in a couple of hours or days, except me. I phoned them, as normal a nice smily tone on the phone saying the application has been received and no dramas
