Ohh...  I also has been use this creator, and don't look that pad 
reversed. Now, I receive ordered board from manufacturer try to put DDR2 
chip to their place and... Oops...
(DDR2 chip has six absent balls that may be used as key).

To fix bug in creator very little patch will be enough:

132,134c132
<                var jj;
<                jj=(columns-j)+1;
<                pin_name = column_name + jj;

But I can't find contact e-mail of the author...
You may "save as.."  this page and edit line 132, and use it off-line .
