Hello, I have already created a ticket but was hoping that maybe I could get some help here quicker. I just purchased and downloaded the 737 Classic but am having an error trying to install into XP11. I attempted to install several times to my xplane 11 folder that is on my desktop by default. Every attempt has been unsuccessful when it gets to downloading the components. The error message is: "Unable to download component 737-300: HTTP error 504" Any assistance would be greatly appreciated
