..and next time you borrow a CD, film, software, book ... from someone...it is illigal to borrow any of them.
Not true of any of those things except software when it states as much. However, all of this was based on your original statement which said nothing of borrowing the computer on which the software was originally installed but rather "a copy of" the software.
As to fixing an XML file you didn't know how to edit, this is why you should always make a backup of the things you are working on. You didn't post the whole thing, and it's just too long to go through to try to find the one character which may be throwing everything off. That's the thing about xml, one mistake and the whole file is ignored by the browser.
