Ok again after reading some things about drivers and having no clue how to do anything,
1. I went to cortana bar and typed in 'drivers' and clicked 'update device drivers' under control panel.
2. the section 'monitors' already had a drop down and 'Generic PnP Monitor' had an arrow on it
3. I had no idea what this meant so clicked on it thinking I was looking for something to do with a video playback driver, and I found it was disabled
4. Maybe some updates had disabled it, I don't know what it is or what it does, though I clicked enable and tried checking other drivers that may have needed updates, and was up to date on the others
5. Went back to sky go and then tried playing Cinderella on demand as a test and the adverts started to play, the error had been coming up right at the start of the adverts at the beginning, so this may be working now, im about to test with a movie I want to watch.
6. currently watching the adverts...
7. SUCCESS , the movie seems to be playing... I wonder how many ways to combat the 6030 error i'll find during my time here haha.
