Sorry BOAC if I have confused you. My computer (Toshiba) does not offer the option of F8 at boot but another route via several of the function keys. Anyway, it is in the safe mode ie, "Safe Mode" displayed in all four corners and the icons about 3 times bigger with a much poorer resolution. I am certain that it is in the safe mode. So I try to delete the files in exactly the same way as I would in normal mode ie, find the folder, open it and then delete. This gave me the same result "Cyclic redundancy" unable to delete.
Keef, don't have one sadly but I have tried via the C prompt in accessories to get into the DOS. That's easy but sadly I know longer remember how to get to directory and subsequently also don't know how to delete it. Vague memory seems to remember cd:/c:dir but I have tried all the variations and
Born to Fly, Tried that, I put FSX on on the 26 Dec 06 (Xmas Present) and done a system restore before that but to no avail.
I am certain now that if I want to kill whatever! Then drastic actions are called for ie, format c, but before I do that I have to find out all the originals and more importantly the license keys to make them work. Sadly like most that is not as easy as it seems. Like most I started off with the best intentions keeping everything filed but over the years and 2 adult (kids) doing whatever they want that just might not be as easy as it sounds.
Blacksheep came up with something that might help here but I have no idea how to do it or with what consequences.
Thanks everybody for your time
