Addon domain not working

[diethylamide]

Hello,

After my old domain expired I got a new (different) one and set it up as an addon domain in cPanel, but the change hasn't seemed to take effect anywhere outside cPanel. The new domain doesn't work, and my account control panel still shows my old domain's settings under "Modify Domain". I've tried changing my main domain to the new domain but that hasn't worked either; I always get system errors. More info that might be relevant: I've already transferred the new domain to X10's nameservers, the subdomain linked to the new addon domain works, and my account was one of those that got wiped by the Boru upgrades.

Any help appreciated.

The domain works now. I've never seen it take so long before, but apparently DNS propagation really can take "up to 48 hours"...

"Modify Domain" still won't let me modify domains at all, but that isn't really as critical.
