I am new here so do not just attack me about random stuff please.
I purchased X-Plane 10 North America about a year ago. I was satisfied with this so I bought the global upgrade to the North America sim. After receiving the discs, I downloaded the content via a disc drive and then inserted disc 1 of North America. I attempted to set my starting point in London (EGGL), but I got the message that I was going out of my zone and I needed to have the global version. As instructed I swapped the disks with GLOBAL DISK 1. Same message. I do not know what is happening. I really do not want to buy another copy of this sim. Thank's in advance. If you could just give me step by step instructions that would be the best.
