The engines do not start

With the latest versions, the engines won't start; the rotor moves slightly and then stops. The same thing happens if I do an engine startup. I haven't changed anything, just updated the 135. It worked fine before, but not now.

I'm forced to start with the engines running. Could I get some help? Thanks.

Did you check this  www.rotorsim.de/de/forum/englischsprachi...topic&catid=4&id=102 ? 

Yes, I've checked and tried, but the problem remains. To fix it, I need to assign the throttle function to an axis.
However, in general, the previous versions worked better. With this one, I experience unusual over-revving during start-up, and when I lift in collective, it tends to initially go down and then go up. This didn't happen before; it was flawless.

A throttle must never be assigned! Unless you want to use manual control in the Plus version. In that case, it must be properly calibrated once with the helicopter loaded.

Check if another plugin is interfering with the throttle control, as XPUIPC does.

Removing all the plugins works fine. Now I'm trying to launch it using one at a time to rule out the one causing the problem.

When I launch it, however, the warning in the picture appears.
