Since upgrading to Across Lite version 2.1 for Mac OSX Lion, I am unable to create .puz files. The instructions supplied by Literate Software simply do not work. According to those instructions, I should be able to open my old text files, which I once used to create .puz files using an older version of Across Lite, but when I try to do that here's the resulting error message: "Unable to open crossword -- This may not be [a] valid Across crossword or it may be corrupted." I tried editing the text files in TextEdit to conform to the new version 2 of text files, with the same result. I even took the sample file from the instructions, cut and pasted it into a text file, and again achieved the same result. There's not much available support from LS.
