The community member purchased an LTD (Limited Liability Company) via Rockethup, but can no longer access it because the domain has changed. The community members discuss the issue, where it is revealed that the email address has changed from [email protected] to [email protected], and the community member can only log in via Google, preventing access. The community members suggest the community member should send proof of ownership of the account with the old email address and the new email address to the support team at [email protected] to resolve the issue.
