Regrettably we can't assist with specific account issues here, but something strikes me as curious. You mention Plesk and the Website builder (trial). One relates to a hosting account and the other relates to the builder which has built-in hosting.
You would need to set the DNS and use (publish to) one or the other.
Please contact 24/7 support to look at this.
We'd be happy to hear if you find out what happened if others would benefit from it.
