I did some of the testing on Ave33's libraries and found them rather nice on both of my 3.2 PT SGC displays and I believe there is support for the OLED things as well. To the best of my knowledge his Picasso support is still limited or was back in July. There were good examples and good (I thought) documentation for the SGC modules from Ave33 or at least in the common package I downloaded and used. As to the Display not working you need to do a little more than complain about the issue because on the strength of the information so far...
I'd have to say "Take 2 and call me in the morning". Without the sketch and a picture of your connections and/or a schematic... as well as an accurate description of the issues. They'res not much more I can do for you.
