Java to CRIO connection problems

[BoltAction]

We have been trying to upload the code to the CRIO for 3 days now. We keep getting errors. We have already tried reimaging the CRIO but still getting the error.
We are using direct connection between the CRIO and the laptop.
The laptop's ip: 10.10.9.6
subnet: 255.0.0.0
Gateway: 10.10.9.4

This is the error we keep getting:
Host OS: Windows 7 6.1, 6.1
Host JVM: Java HotSpot(TM) 64-Bit Server VM 22.0-b10
Target IP: 10.10.9.2
Network interfaces on host:
