Conflict VirtualWire ServoTimer2

Hey,
i´m writing code for a RC-Car and have a problem with controlling a servo.
I want to send data from one Arduino to another and steer a servo there. I use ServoTimer2 to not get in conflict with the timer of vw and the servo-library. But when i try to controll the Servo i can´t receive new data anymore. Controlling the Servo without vw is no problem. I tried even a few other pins but it doesn´t change anything.
Has anybody an idea where the problem could be?

Maybe in the code that you did not post?

Check whether the above uses Timer1, in conflict with VirtualWire.
