Can't sign app with private key

Built my first little app using the Corona flavor of lua, but I can’t seem to get it signed with my key. I’ve used this key hundreds of times for over 50 published apps so I know it’s fine. And I can use the debug key included with the Corona SDK. But when I build for release and point to my keystore, I get the following message every time.

Keystore was tampered with, or password was incorrect

I’ve tried over and over, rebooted, closed everything, stood on my head, sang the national anthem - nothing works when I use my key.

help?
