I did try calling to confirm all was well, but gave up after 1 hour on hold. Anyone have experience with this situation? It seems to me that the change went through but the glitchy online system just threw an error message for no reason. I also never received any auto-generated confirmation of the change, though it will let me email the itinerary (showing the new flight) to myself.
Try clicking the "add e-mail address and request receipt" button. Then either wait for an e-mail or wait a couple of minutes and click "view receipt" on your online itinerary view to see your most recent e-ticket.
If the flights shown on your e-ticket match the flights shown on your reservation, you are good to go. (If all the new flights you want are operated by United, you are probably also good to go.)
