R4i-SDHC Firmware 1.22b Error

Hello Community,
well here is my problem:I wanted to update my R4i-SDHC with the newest firmware 1.22b [German], I downloaded it from r4i-sdhc.com . But when I want to start the flashcard than I get a white screen or an "Error" written in red. I'm using an DSi with firmware 1.4 ! Does anyone have the some problems, is the firmware of R4i failed or is there something wrong with the DS / Flashcard?€dit: I downloaded the older firmware 1.21b and it works, so it should be a mistake in the firmware, I think. But other answers could be right too

the new firmware is not working for me too (dsi with firmware 1.4). maybe someone else has better luck?

Maybe it is a bug with the firmware. I cannot test it (I have first generation card T.T).In the meantime, you must use a previous version...
