I think this balance of yours is gone since the site has been reloaded into it's next version for a couple of weeks now.
From what I understand your old account will no longer be accessible and you were to create a new one if you wanted to continue using the site.
Sorry to tell you this but wanting to save on the withdrawal fees cost you your $100 worth of bitcoin you left in your account.

Huh? This is definitely not true. No one's balance or details or anything has been affected. Any money on the site (even if it's been inactive for 3 years!) is still completely and instantly available.
And FWIW, the withdrawal fees now are extremely low. It's currently 34.34 bits (~0.28 USD) to do a (non-instant) withdrawal that gets processed within a few hours or so. And if you want the withdrawal instantly, it's an extra 139.38 bits (like 1.15 USD)
