Problems programming Arduino Mini Pro with FT232RL USB To Serial 232 Adapter

[system]

Hello together,

I would be very grateful if I got assistance with my problem. Please forgive me if these are noob questions, but I am very new to the whole Arduino thing. I have managed to program Arduino Pro Minis in the past using an "USBasp" and connecting it to the Pins 11, 12, 13 etc on the side. This worked well, but now I want to program it via the end pins.

What I have, are these devices:

The Arduinos work, as a matter of fact, the one I'm trying to program at the moment was successfully programmed via the side Pins.

First of all, I have no definite idea which "Programmer" to choose. So I tried them all, but without success. The least scary error message appears when I use the two at the top (AVR ISP (mkII)):
avrdude: stk500_getsync(): not in sync: resp=0x00

I will include some images of my computer setup.

I tried to install the newest drivers. When I tried it at the top (USB Serial Port (COM13)), It said the used driver was the most current one. When I tried it at the bottom (USB Serial Converter) it installed a new driver. Both devices seem to be the same though.

I found a video with a guy trying to do the same thing:

Arduino USB-to-Serial Tutorial - Programming the Pro Mini

1 min into the video, everything looks exactly as in my screenshots. I also connected my Arduino and programmer the same way he did. I swapped TX and RX several times, but no success. Power LED of both programmer and Arduino light up when connected. Jumper sits on the "5V" position.

I'm using Win XP SP3 on a Thinkpad T60P.

Any ideas what I did wrong?

Thanks,

Julian

Thanks for your answer. I just did that, and the process did "something" to the Arduino. The blink pattern of LED 13 changed. I could change the pattern back by programming it with the blink program via the USBasp.
Both times, I get the error:
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
But I get it always when programming via USBasp, so I do not consider it critical, at least not when programming. Maybe uploading the bootloader is something else?

However, this did nothing to my problem with the new adapter I have. I still can't get it to work. Could you tell me which "programmer" I have to choose, so that I do not always have to try all of them out?

Thanks,

Julian

Did that, swapped RX/TX, even installed new 2.10 driver, but the error persists as before...
