Deleted my profile when converting guest to member

I've just had this problem on the AUT site. I got my profile overwritten by a guest - not the one I was upgrading to a member. There were two versions of the guest and I deleted one. What do I need to do now?

What is the guest's name?

Remember that nothing really gets deleted for MM any more, so as long as you do not make further changes, we can probably recover the situation gracefully.

I was out at a meeting, hence the delay in replying.

The guest's first name is Thomas. I see that there are two identical entries with that name in the guests list. Are you saying that one of those is really me?

Yes

Ok, you are back. You will need to reset your officers, though, unfortunately. Sorry about that.

Thanks!
