Programing Mini using Uno

Hi, I am trying to program an Arduino Pro Mini, using the Arduino Uno Board. I saw a video online, and the first time I tried it worked, but now it seems to keep giving me an error message: "avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x11"
I have no Idea why this is happening, all cables are connected correctly:
Uno -- Mini
5V -- VCC
TX -- TX
RX -- RX
Reset -- RST
Once again, I have uploaded code this way before, but now its not working. Please help.

Shouldn't it be TX --- RX and RX --- TX ?

I also tried that and I also get similar error messages.
