Alt checkers

Is there any account crackers/alt checkers that show you the username of the account, for migrated accounts? I have over 10k alts and half of them I don't even know the username for... Or if I'm looking for a specific alt that is migrated, it's nearly impossible to find it. And am I the only one that can't open EggCrack or launch the Flare hacked client? They both crash on startup with some error from java about account login something.

Here's the EggCrack error


Here's flares.

I use the alt manager in Flare and once you login to the account it displays the name. And when you are checking them, you can use a program called "Cat Checker" and it will show the name, skin, cape aswell.
