My STF-8300M will no longer connect to Win 10 Pro laptop. Receive " Error on open device:27". Downloaded/ran Driver Checker; received notice drivers etc are correct. Laptop Device Manager shows SBIG present with exclamation point. Update no joy. The cooling wasn't working well recently so I had Bill L replace the cooler board/chip. It subsequently connected when I checked the cooler performance. Unfortunately it failed the next time I tried to connect. I asked Bill if there was anything in his bailiwick that would fix the problem but he suggested I contact the DL Forum. Have seen some prior discussions on the forum related to Error 27, but can't find them again.
