Can't flash OTA file using TeamWin Recovery on HTC One

I have HTC One, with custom recovery, bootloader unlocked, and rooted.

I got the OTA by from Settings - Software Update. After downloading, I wanted to flash the ZIP file in Recovery mode. But when I want to flash that, after 5 or 6 seconds, it says failed because MD5 can't be founded. I already downloaded this file 2 times because I thought the file has problem, but the file seems to be okay.

What should I do?
