Do you have the newest wallet installed? Version v0.1.5.21-unk ?
There was recently a hard fork and SHND owners need to install this wallet that is supposed to actualize the blockchain.
In your case, I am not sure wether the coins are lost or not, but you can give a try.
I am also waiting for a deposit of several millions of SHND coins and am waiting for the wallet RESYNC to be completed.
