Okay, thank you NickGolovko for your reassurance. So, this error isn't a problem then (that's a relief - I hadn't a clue what it actually meant). In fact, I have just run a search on my pc and have found that the filename relates to a Roxio Media Creator 7 Storyboard help file which I'm able to access and view in the Roxio program file. I presume that the file found in Windows was just part of the Roxio installation process......am I correct in this assumption or am I just being a complete half wit? Sorry to sound so dumb............
