I do have lots of tips, but I don't know what you are referring to.
Perhaps a PDF of the manual can help?
Use Adobe acrobat reader to read it, if you can't open the file. http://gdlp01.c-wss.com/gds/6/0300012156/01/pssx170is-cu-en.pdf

You could try to format the card in your PC (format FAT32) and then try to format it in the camera again. It could be that the filing system had been corrupted and the PC format will remove the damaged file and by formatting the card in the camera the filling structure will be reinstated on the card. Hope this will help!

update firmware might help sounds as if you might want to get all the pictures off of it ect . bad products seem to be the norm these days

Since I cannot see your pieces, I can recommend actual replacement. You can Google your camera's make/model with replace lens cover and pick from the listings. You can also go straight to Canon USA and search their store as they have replacement lens covers. I did this here for another customer as an example.
