TLR46 Software for Rotax914

I managed to run the tlr46a software on my windows 10.

Now i have the following problem: „ERROR: WRONG TCU VERSION! Continue with any key ....“ is coming up.

(I use PN 966 741)

Any idea, what is wrong??

I think it's the USB - Seriell Adapter, ordered a new one.

Update: Thanks, yes, it's working now, it was the USB-Seriell Adapter?
