Very helpful Xyon. However, as you may discover when you are a bit older and more experienced, it is not always necessary to provide masses of information. Alain may well immediately realise the problem from my brief description - if not - I will be happy to provide more details at that stage.
And in turn, as mentioned, very condescending. I have no idea who nor how old you are, nor was it my intention to do anything other than save typing out the same questions I repeatedly find myself asking people posting such vague problem posts time and again, which was indeed the reason I wrote the article.
Orbiter.log and Orbiter.cfg are hardly "masses" of information, rather they are as I'm sure you're aware extremely helpful files when it comes to troubleshooting, and nine times out of ten the answer to your problem is within them, which is why the first question when the contents are not provided is usually "What does Orbiter.log say about it?".
I'm not sure how much more experience you believe I require, nor how much older I need to be to adequately troubleshoot, but rest assured I will refrain from attempting to assist you with technical issues in the future.
