Glad to hear you've got everything working now. I'll give you a few tips regarding the .cfg files to take the pain out of editing.
1. ALWAYS make a backup of the original .cfg file before you start editing, especially when you're still trying to get the hang of it all.
2. We mostly deal with aircraft.cfg, panel.cfg and fs9.cfg files, though there are others which you might come in contact with at a later stage.
3. ANY type of .cfg file should by default open with Notepad. If it doesn't, right-click on the .cfg file and select Open with... and Notepad from the drop-down menu.
Alternatively, you can right-click on the .cfg file and select Properties from the drop-down menu - you should see: Opens with: Notepad --- if it doesn't say Notepad, click on the Change... button, find Notepad and click on it, click on OK and lastly click on Apply.
Sounds complicated but isn't. Now all of your .cfg files should by default open with Notepad when you double-click on them.
4. Some .cfg files can contain thousands of words and to find a particular entry can become very frustrating by reading the whole thing.
Just hold down Ctrl and press F and type the word(s) you're looking for into the Search bar.
Any problems, don't hesitate to ask.
