USBAsp and KK2.0 Flashing woes

When I fkashed my first kk2, I did it using the usb avr programmer that came with the KK 5.5. It did not work with the official usbasp drivers, but I'd found a video somewhere on youtube that showed how to use it by installing libusb. Now I can't seem to find it anymore. This was when I had a 32 bit version of Win 7. The flashing worked without a hitch, and I also flashed a few escs.
Now, I've got Win 7 64 bit, and got the HK Usbasp programmer after giving away my older one. The drivers installed without a problem, and they're also being recognised. Now when I'm trying to flash my new KK2.0 boards, the kkmulticopterflashtool gives an error:

Flash the firmware from repository.
Error during writing flash.



But, when I use an already downloaded kk2.hex file It flashes, only giving the cannot set SCK frequency error, but it flashes it:

Flash the firmware file.

avrdude.exe done. Thank you.

Flashing of firmware was successful.



I tried flashing turnigy multistar escs with the same setup, no problems. The software gets the files and flashes it. I just flashed six of them. I'm only having problems when I have to flash the kk2 firmware from the internet

So, what's happening, any ideas? Is it some driver error or something else?

There is a checkbox "cache firmware" top left. Does that work?
Maybe the tmp/cache directory does not exist or the program does not have the rights to write the hex files there?
 
I'd already tried caching firmware. After I've ticked all what I want, the click download, it just hangs. Happens everytime. Therre are files in the tmp directory though.

Maybe there is a corrupt file in the tmp? Just guessing. It is strange because the tool usually reports what is happening
