The Dink Network

For finding save files, you could try going to your Dink directory, then Cloud Castle 2 folder (which is probably called "cc2") and then copy the save#.DAT files (or just the whole cc2 folder) to where you installed the older version of Dink. I think it will work but I'm can't be sure because I haven't used DinkHD very much.
