Looks like pin to track clearance causes some of your problems, you may enable auto enforce drc and try to route track manually between pins and see if it fit at all, if not then change clearance lets say to 8mil, and try again. Usually its doable to place one track between two adjacent 0.1" spaced pins, i was told that one put two tracks between them, but i haven't seen that myself.
