As for having gotten a bad rack, this is an entirely reasonable result for a lot of racks. The don't all just fly apart in Thorsten Hohmann style. A major part of 14.1 is learning how to deal with the intermediate breaks including getting good angles, having insurance balls, hitting clusters just hard enough to mostly loosen them up, etc.
In the Virtual Pool shot above, it would probably be better to take some of the follow off the cue ball to hit the 13 so you keep the cue ball closer to the center of the table. That gives you more chances for a shot in case you can't plan on anything specific.
