Absent some other time set by the court, the rules of civil procedure would apply to the time-frame to respond after the denial of a 12(b) motion to dismiss. The application/affidavit for default filed before the Motion to Dismiss is no longer workable - the filing of the Motion to Dismiss is a responsive pleading that is required by the rules and precludes the entry of default. If there has been no answer or subsequent motion allowed by the rules a new application for entry of default would be appropriate. You may want to check with the court to make sure nothing has been filed and simply not mailed to you correctly before filing the motion.
