@N293WK Thank you very much. This was indeed the problem. @Derek I never received any feedback for my open support tickets. No I cannot even login any more as the page "log in as customer" comes up with "file not found"... Glad I got the issue solved from this friendly formum. Thanks to all
Is there any way of dialling down the levels of sound volume on the Hawk? At present the volume of all sounds appears to be out of step with other aircraft in the sim. As a result, when loading up the aircraft having previously flown something else, it's necessary to turn down the master volume in the sim settings in order to hear yourself think. Then, when switching to any other aircraft, you need to remember to turn up the master volume in the sim again.
