After adding  a statistics counter to my website and after pressing preview, my template and lay-out design was screwed up (I removed the statcounter code after that). Although I didn't exported it to disk or the internet, it keeps loading the wrong design and I can't get the original back again. Before uploading to Internet I always use the "export to disk" option first, so I have a copy (made yesterday) on my harddisk. But how can I reload this to get the original design back??  

Please help!!
