Vinny,
Same problem with a buddy of mine, but with withdrawing LTC from Vircurex. Sent 1 LTC, no problem. 25 minutes later he sent a larger transfer out of Vircurex 500LTC and no Transaction ID appeared and it never hit the blockchain. Checked several explorers and the transaction is not there.
If I were to play a guess, the 'hot' wallet for the exchange might have been dry and the admin might need to move LTC from the 'cold' offline wallet.
My friend still awaits a reply from the admin.
Please update if any of y'all get an update from Vircurex administrators.
The hot wallet thing makes sense.
I've emailed customer service twice but they still haven't gotten back to me.
I sent Kumala a PM as well.
If I hear back from anyone I'll post about it here.
Vircurex seems to have experienced problems with deposits and withdraws in the past and they were resolved.
