Today I upgraded from 1.0.1 to 1.0.3 and experienced problems verifying files. I could not verify a file with GPGee or WinPT. The files had been verified under 1.0.1. GPGee said I had an invalid key and WinPT did not show any results. GPA did verify the file. I re-installed a second time with an uninstall, reboot, and install to see if was an installation error by me. I got the same errors. I have reinstalled 1.0.1 and it verifies the files again.
