Can you confirm that FIRST 2.29 firmware is loaded on the 2CAN?
The 2.29 crf is in the zip with the bdc_comm.exe on our website.
2CAN Firmware version is at the bottom of the webpage and also can be retrieved thru the firmware utility.

That error can happen if BDC_Comm can't "find" the 2CAN or if it fails to load the DLLs it uses to find/connect to the 2CAN. Can you confirm that all the files in bdc-comm (CTR-2CAN supported) - 1_7_2013.zip are uncompressed together in the same directory. The directory should have a bdc_comm.exe, along with bdc-2can.dll and 2CAN_Comm.dll

Since you can get to the webdash I'm thinking something else is stopping bdc_comm.exe from finding the 2CAN. Usually it's a firewall issue. Are you connecting an Ethernet cable directly between the laptop and 2CAN or going over wireless? It shouldn't matter but a direct cable connection might help narrow down the issue.
