Hi,
A couple of other points about this:
- I have just noticed that on the new update there are some area labels missing (EGPX and EGTT are the two that I have noticed) from the map view - MD11/B712 ND gauge. I'm pretty sure they used to be there and thought it might be due to my tinkering with the text files, but I put back the original backup text file and the problem is still there. See attached!
- For more current boundaries, have a look at this link: 
http://www.ecacnav.com/downloads/RVSM%2 ... een%29.pdf. Initially it might seem like a big task to re-do all the areas but actually there are only a few name changes and merges needed. Almost all the actual boundaries are unchanged! This is list as far as I have worked out for Europe.
