Glad you got it fixed, wonder what the issue was, as the CWIL is effectively a "dumb" board used for interfacing... IDWT do you know if there was a firmware issue with the CWILs? I saw a release but I honestly have never had any issues with CWILs or CWIKs for that matter. I usually find it was me being stupid and having my low and high reversed or something not seated properly...
