As you can see, the address is present in the wallet, and the blockchain is up to date, yet the balance reads zero. If anyone with the correct privileges feels it is appropriate, I would very much appreciate a repost of this in the main tech support section. 100 btc to anyone who can help me solve this problem. Thanks!
That certainly is a lot of BTC, good luck in getting them back. From the sounds of it the rescan is exactly what's needed.
