At this point... if you're good with HTML (or can use a designer such as Dreamweaver, whatever) I would honestly start over - start from scratch and just use that template as a guide visually (not coding-wise).
EDIT: Though, you never know, perhaps some one will come along and help you untangle it. I just tried to quickly drop it into Dreamweaver, but it was pretty obstinate and wouldn't work quite right, and I didn't really want to sift through all of the HTML and try to find an imbalanced row, wrong colspan count, etc. - something that threw off the rows in the table. Sorry!
