I can only provide information about the account that is related to this forum account (which in turn would be associated to r**i@lay****ey.co.uk email address, ** does not represent actual number of chars).
This account does not exits on the new system, not for the panel login nor on DirectAdmin, your login records are somewhat spotty and between november 2019 and May 2020 you did not login once, this would have lead to your account being purged as inactive in March of 2020 when we did a manual run to clean out the system of inactive accounts. It could have been at a later point as well, as your next login (to the SSO page we used back then) was in October 2020 which a large enough gap to consider the account inactive, the requirement is to login at least once every 30 days.
As for the other account, you would need to login to the forum account you had associated with that so I can look it up, but regarding this one, you would need to sign up again and upload any backups you have if you want to restore the site.
