Where did you download that cracked launcher?

For future reference, what tipped you off that he has a cracked launcher?

[EvilOwl]

Unusually old launcher build is the biggest hint. If a user has problems with the launcher he downloads it again, it means he should have the latest (more or less) version (around build #313 at the time of writing this).

The second one was googling the stacktrace. It lead me here and here.
