well... that's a little disappointing...
Found 3 valid private keys out of 9,663,676,416 combinations... and none of them were the right one (or had any BTCs
) So, obviously, some of my assumptions were wrong 
We really need to solve the mystery of whether or not there is any way to determine upper or lowercase based on the information we have... I have not been able to discern any pattern as yet...
