The other day I can across another schematic software. it is open source and does not have that 30 days time limit that seems to change on you. Dip trace trial did the same thing to me but I think it started at 22 days.
Main project page:

Device libraries and modules
http://www.kicadlib.org/
at the bottom of this page is Unclassified packed library there is a couple of rather large libraries there. Make sure you put the .mod file in the modules directory and the rest of the file n the library directory.
It does have the ATmega devices but I had to edit it to look similar to what was in the original circuit diagrams
It appears to be similar dip trace and other types of schematic software I have been looking at. I have the Main board schematic redrawn, and just started playing with the pcb part. Once I get them done I will post them all here, for others to use if they want to.
