The update is mostly the debugger (the BC panel). The fixes were pretty minor (e.g. making some changes to one of the fonts).
Do you still have a file called msn.dat somewhere? If so, that has your progress. Put it in the same directory as the executable (Libcirc.exe).
That design looks okay, as long as you can point it in the right direction so the back doesn't get destroyed. 63% is a bit underpowered, though - you could try using a more powerful core (if you've unlocked the next one) and see if that makes it survive longer.
