first of all, have you checked that you use the lates driver and the latest PCAN-Light DLL Versions?
http://www.peak-system.com - Support - Version Information. If you do not have the latest Versions, please download from the Support page.

As we understand you have 2 differnt CAN Channesl (independend from each other) So please check the CAN Bus where the Channel2 is connected to. Have you terminated the CAN cable? Is the other CAN node on the 2nd channel initialized with the right CAN Parameters?
If you have checked this, and the error ist still there, please send a E-Mail to support[at]peak-system.com with a detailed description of your system - we will try to fix your problem soon as possible.
