A CRC error is a cyclic redundancy check error and it pertains to the software or file being corrupted. It has nothing to do with the board design or routing itself.

Perhaps you meant instead a DRC error which stands for Design Rule Check error... these come about from some feature not meeting a global rule.

Each error must be inspected in turn to see if it is a real rule violation needing to be fixed (rerouted, moved, whatever) or if the rule itself is improper (such as not allowing pads to be placed close enough to accommodate the IC's in your design).

In this case CRC=Connectivity Rule Checker, and not cyclic redundancy check

CRC establishes which pins are connected to each other (by tracking and vias) and compares this with which pins have been assigned to the same net in the netlist. If you click on the items in the list, the net or nets affected by the error will be highlighted. If you design from a netlist in the first place, and especially if you use the auto-router, you are unlikely to make mistakes other than missing connections out.
