Subdomain not working with domain.

[lithiumlabs]

Hey, I have a domain, lithiumlabs.net and there is a sub-domain setup as forums.
This subdomain forums.lithiumlabs.net worked when the site was running on lithiumlabs.x10hosting.com, but since I changed the Main Domain to lithiumlabs.net, the forum sub-domain no longer works.
I have tried removing the subdomain and adding it again but that doesn't work either.

EDIT: Please close this thread, the issue fixed itself. Funny how computers do that

Confirming that the url ->http://forums.lithiumlabs.net/ works fine.

Issue solved, closing this thread.
