Aerofly 5 not booting up properly

[PassinThru]

I have Aerofly 5 (5.7.1.1 update). My setup is JR 9503 > Aerofly interface cable > Aerofly cable adapter > Aerofly USB stick directly connected to a 2010 iMac. When it works I can usually run it at 4x aliasing, high resolution and 60 frames per second.
The problem is that the simulator only boots up properly once every 50 or so attempts. The rest of the time it boots up to the last field I selected all right, but while it says it's loading up a Trex 700E which is my default sim heli, instead a small blue and white high-winged plank shows up on screen, with a dialogue box telling me that the program failed to detect a controller. This usually goes on ad nauseum until I give up trying to re-boot.

I have contacted the Ikarus Support Team but a response is slow in coming.
I wonder if any of you Aeroflying Freaks can contribute a solution.
Thanks in advance.

The folks at Ikarus suggested re-installing the program. I re-installed the latest update 5.7.1.1 and then removed all the update files from my Aerofly 5 folder in Applications. Since then it has started up twice with no problems. It's been a while since that's been happening. Now to get ready for spring.
