Hi, 

I have some problem about back testing.

I havn't logged in for several days until just now. But when I run back testing there's an error shown up. 

Could not load file or assembly or one of its dependencies.      (Open Stacktrace)

click Open Stacktrace, the message then shown as below:

at QuantConnect.Lean.Engine.Engine.Run (QuantConnect.Packets.AlgorithmNodePacket job, System.String assemblyPath) [0x0062a] in Lean.Engine.Engine.Run

(QuantConnect.Packets.AlgorithmNodePacket job, System.String assemblyPath) [0x0062a] in :0

 

Please help. Thanks in advance!
