Force Feedback work only the first time

Dear Shaul,

Many thanks for your fast replay !!

I have already tried different times to disable and after enable with vJoyConf but the result not change.

To better understand the situation, I send more detailed informations:

One year ago I was installed the version 2.1.8.38 that was work perfectly (Force feedback included) and I was not found any issue.

After installed windows 2019 May updated (this is an auto update) the force feedback stop to work (the only way was re-install vjoy each time).

I installed the last version 2.1.9.1 and the force feedback never work and at this point I come back to previous version (2.1.8.38 and the force feedback work only until I will not re-boot).

It is clear that windows update was changed something that was interferes with vjoy but I don't known more ..

Any suggest ? there is a way to solve it ?

Thank you !

Marco
