1MSfcqR5wbNhqypauTkSaf6nbWyrEBiRh6 is the regular one
12X3ZrbDhY3norV3HcQaC5AcSsriwpmk1Z is the compressed one, the one I sent BTC to when it was supposed to go to the regular one. Since I had (them) generated by a BTC client, would the keys be required to check? I just don't know how unless there is a button next to it that says ' send'. Sad, but true...
