I’m not sure about that RER but older software didn’t support the valid floors parameters yet so probably nothing wrong there. There are basically 2 types of CLC cards. Old ones like BP1, BP2 and the first one that just had a number and then there is the BP4. Software is not interchangeable between the 2 types. DK13 is the latest for the BP4 boards but for the older it’s AN13. If you have an older board and all you can get is a BP4, you will need new software.
