RM Recovery

I am in the middle of RM recovery testing using the following script:

run
{
set until time="to_date('12-13-2012 10:10:00','mm-dd-yyyy hh24:mi:ss')";
restore database;
recover database;
alter database open resetlogs;
}

Somehow, it stopped at what it said 'unable to find archived log'. I have located the log files now and the rest of them, is there a way I could resume the recovery.  The prompt is still at RMAN>

One more question is that I specifically configured the script to recover until 10:10:00,  the log file it said couldn't find is after the 10:10:00 based on last modified in the file.  Don't why it needs it?
