I don't know for sure, but I don't think they do a second round of credit checks.
Looking at threads for previous years everyone seems to have gotten the credit check at the same time. Also, in last years thread on September 17th someone received the award (I'm assuming one of the last awarded). That person said they had gotten their credit checked with everyone else in July.
Since I didn't get my credit checked I'm assuming that I'm not in the running anymore. That doesn't mean I've stopped checking my email!:)
