I live in Canada and have just received a Sony Reader PRS-505. While it is wonderful "gadget", I cannot order any books from Connect e-books as I do not have a US credit card. I understand that there are two downloads to use that will assist me in converting Microsoft E-Books to Sony Reader compatible books (convertlit and libprs500)

. How in the world do you use these programs? I am not very computer literate and I am having a lot of difficulty with this. Can someone help me out?
