HTML page re-editing (2002-2005)

Hello,

I made a web site with PShop and GOLive back in 2002-2005, I do not have PShop or GOLive anymore, but i wish to edit the path adress of those html pages generated by PShop and GOLive in 2002-2005, all i have is PS Elements10 and it does not recognize them, and none of my other programs will open the HTML pages so that I can edit them, I need some answers about how to maybe fix this problem?.

Thanks for your time

the site is neonskys.com and you will not get past the index.html if anyone is interested?.
