No buy signal

I received my first signal for Spiderman system by email a couple days ago and it is an opening signal, not a closing signal. However, the signal was not received by my autotrade software and so the trade was not executed. The software was running and it was polling for signals at the time. I searched the log several times in different ways and it is not there. Anyone have any ideas why I did not receive the signal? The holding does show up in the cmd=requestsytemsync response so the autotrade software is connected to C2 and running properly.
