Firmware upgrade doesn't work

Hi,
I finally managed to get to the firmware upgrade page and tried to upgrade to the latest fw. The MCT reported a successful update, but the MD display was stuck with the "Send Sysex now" message. After rebooting the MD it showed the old firmware version on the fw info page.
It's a Synthex kit3 with Atmega32/16MHz/32 inputs, so the syx file I tried to use was megadrum32_16_32_20090528.syx. The old fw is v 090430.
What am I doing wrong?
Endre
