Subject: upgrading problem
While trying to update my OS for the 83 plus, my calc tells me it's low on batteries (they were new, so I have no clue how that happened). Then after replacing the batteries and turning my calc on it just reads "waiting... please install calculator software now." when ever I try sending the OS from my computer over the thing just goes "ERROR! Press any key to turn unit off then turn unit back on"
