Error opening URL

Hello, I’m using Macromedia Professional Flash 8 and when I try to view my slide show on the Photos page, while trying to edit it, it says:

Error opening URL “file:///C|/Documents%20and%20Settings/Canada/My%20Documents/Internet%20Website/fla/guest_thumbs/th_0.jpg”

Also on my website, I don’t know what I did wrong, but it’s not aligned right. please view after you click the splash page to enter the site, the template is to the left.
