There's nothing TO solve. You've decided that his rather inept questions mean there's something in your background that he (or someone behind him) knows; something about you that (they) know and you do not and you've got to run out and fix it.
That is, to be perfectly honest, nonsense. But if it's worrying you, let's examine this. While I have very, very serious doubts that this is the case, it's remotely possible that there's an error out there somewhere. Have you run a recent credit check on yourself? Or a background check? If not, then do so. There are plenty of online places where you can do that for free or a very small sum - I'm talking less than $10 - most of the time less than $5. I won't post recommendations on line but if you want to PM me I'll give you the name of a reputable one.
If something comes up, you'll know what to research. But, if as I strongly suspect, nothing does, will you please just calm down and forget it?
