@Jasper Hm... is wrongly there a self-correction? I would expect to see wrong there, haha.
I normally see wrongly used before the verb (His name had been wrongly spelt, from LDOCE), or when it's meant very literally (can't find an example now). LDOCE also has You've spelled my name wrong -- there should be an 'e' at the end.
They knew they had acted wrongly – from the OALD.
This is the "very literally" case I mentioned.
I don't think wrongly is a mistake there; I think it sounds a little more formal.
I probably use it all the time, but that's because I try to avoid thinking about word choice like that as much as possible. I do the same with the possessive thing (mind my/me asking), even though I know the former is more formal in most cases, and even unnaturally so in some.
