New Devo 12S and first problem

Hello,
since a few days i have my new Devo 12S. It works great with my Master CP, V450-D03 und Super CP.
But now i want to create a airplane with flaperon. But this does not work. If i choose it, in the servo monitor i can see R-Aileron and L-Aileron, but they are standing at the side not in the zero position. I am looking in every menue, but i found nothing to change this.
I am from germany, hope to understand what i mean.
Regards

Question is are you running Deviation?

I can't help you with stock firmware and this is the case with most users here.

Thanks. Now i have tried to install the deviation Software, but it will not work. First i have install the 3.0 dfu file and then i have format the drive. After that i have copied the files from the deviation-fs-devo12-v3.0.0.zip to the drive, but then there is always only a blue screen on the 12S nothing else.
Can someone tell me what is wrong.
Thanks.

You have to install also the .Lib file.

Edit: yes, my apologies for being so brief witrh the wromg file name, I meant the devo12-lib.dfu as Vlad said below

Do you mean the file devo12-lib.dfu?
There i always get an error message from theDfuSe,
"Unable to find data for that device from the file"
