hi, I’ve got an stx plugged into to a windows 7 machine that has worked fine for ages. Went to connect last night and couldn’t. Just sat there hanging and trying to connect. The error code was 300001. I thought it could be the computer or the cable or software so got a new cable and a MacBook with ccdops software and plugged it in. Had the same issue. Camera is definitely on. The fan is whirling and I can see lights on inside it. What is the next stage of troubleshooting? Thanks, john.
