I tried to access her stream, and my computer seized up so I posted in case it had happened to anyone else. No-one commented, but just in case someone else does meet a problem, i'm posting the aftermath. After a night unplugged it was still crashed on KJK's site so I booked it in the local fixers. Took it there, the guy plugged it in and lo, it started, and could move away from KJK. I've now cleared the history.
But, all is not well, because my McAfee software has vanished, bar a couple of icons which don't connect to anything and I now have windows Defender popping up instead. Not happy.
