But it could be the Front Derailleur is not parallel to the chainrings any more. The arms that move the chain on the FD must not be at an angle to the chainrings. Loosen the clamp and bring them back in line, being careful not to let it slide up or down on the seatpost.
If all is well: Prop up the back of the bike and while turning the pedals by hand, shift the FD and watch what it does.
It probably has nothing to do with the chain UNLESS there is a twisted link. This would be very obvious as you turn the pedals.
