MessageQueue.ReceivebycorrelationID()

Question

CorrelationID : @"865c7cf8-8aa9-46a8-ac62-133b57baa8bc\4131" .
     This is the correlationID I pass. But by the time it reaches the method i see it as "865c7cf8-8aa9-46a8-ac62-133b57baa8bc\\4131 ". And the method timesout. I can see the responses in the responsequeue. I have a parallel queue which uploads the queueData into the Database. I even see the data in the database. But when i try to grab the message from queue it says timneout. I am not sure whats the reason. Can somebody give me a suggestion on this?

Thanks,
ambati.
