I don't understand what are you trying to say with "no support anymore" ? Have you read the post I linked which explained the issue and why there's nothing we can do about it ?
I linked to the LAST post, which identified the issue with FlyInside so, there wasn't any need for you to post or look or find any error log. If you are using FlyInside and get an immediate crash in GSX, it's because (as explained in that post I linked), FlyInside switched to a configuration which were made BEFORE you installed GSX, so it was missing the Simobjects lines which are required to find its own Simobjects.
So, the solution should be being sure that all configurations that FlyInside switches to and from, were all made AFTER GSX was installed.
But as I've said in my previous post too, the REAL solution should be that FlyInside should be updated in a way that it won't "just" copy over a whole FSX.CFG, but should only change its own settings, or should recognize changes to the FSX.CFG made by other installers, if only for the Simobjectspath lines, otherwise it will have issues with lots of other installers out there, which can all make changes to these lines.
