Hello!

I have a B450 Pro4 Motherboard and I have the RGB fans of my case connected to the ARGB header.
The Programm worked perfectly for me for one month (except Razer Chroma Connectivity), then it suddently broke and showed me the "This utility is not for this Plattform"-Error(0xFFFF).
After searching for a fix I now flashed the RGB Controller and its giving me the (OxFFFB) Error-"No ASR graphics card and USB Header". It previously working should show that my MB is compatible, right?

Does someone know a fix for this?

Thanks in advance, Toast
