US Cellular version

[shiftmx]

i have been doing research on this for a few weeks. (i know a little overkill, but i want to feel like i done my homework first.) i also am wanting to flash an updated rom to my uscellular 6800. after reading countless posts and threads, there is this one here. http://forum.ppcgeeks.com/showthread.php?t=24511
that is specific to the uscc 6800. the guide at the first post of that thread seems very complete.
i have since dowloaded everything in that guide and i get to step #6 where it says to start using ppckithen buildos. in all the countless other guides i read it says after opening ppckitchen to update it. therein lies the problem, for the life of me i cant get it to let me update anything. it always gives me "cant copy file ppc-buildos.exe." everytime. can anyone give me an idea as to what the problem is there, please? i also have no idea which cooked rom would be the best to use. the guide says to use no2chem_5060. but the guide is from over a month ago so not for sure if this is still the best rom to use. so i have stopped at step 6 untill i can get some help or figure out why i cant update ppckitchen.
