Question: I am an infrequent user of Responsive Site Designer. It appears that that program has been supplanted by Site Designer. I cannot open my website with the former, and I would need to buy Site Designer. Help!

If you have opened your website in a trial version of SD and saved, you should also find a saved version of the original file with a different file extension (don't remember what that extension is, though). When you find it, just rename the file ending to .rsd, then right-click and select 'open with', and then go for RSD.

Hi guys,

If you didn't save the file as a new version before opening in SD3 you more than likely lost the original file. There is no way to go back to RSD once opened and saved in SD3 as they have the exact same file extension of ".rsd"
