I have tried to download version 4 and it starts to download, then after about 10 meg it starts over. It does this about 5 times before it fails.

I've tried 3 different computers and 2 different browsers to no avail....

Help...

P.S. I did download version 3 and it works fine

Not currently, no.

Is there any way in the setup file of changing the flight plan display route to go back to a thin black line rather than this large magenta display?

Please keep your X-Plane 11 database for the time being.

If you build rebuild the database for X-Plane 12, right now you'll end up with 0 airports. (if you've already done this, Plan-G has made a backup, and you can simply copy Plan-Gv4 Files\Data\Plan-G_NavDataXPL_Bak.db to Plan-Gv4 Files\Data\Plan-G_NavDataXPL.db and things will be back to the way they were.)

There will be an update to Plan-G soon to fix the problem. Please check back here regularly for more information.

All sorted now.
Looks like at some point I had selected the wrong locPak, looks like there are a few knocking around in different folders.
Anyway working as intended.

Thanks for the help!

Ah ok!
That's an easy fix then, thanks.

It may be because I have a custom install location.

That means it didn't find the locPak file that contains the name lookups. You should see an entry in the log that details that failure.It's worth checking in case there's something odd going on.

You can specify a locpak file in the build settings dialog (typically this is for non-English languages, but you can specify the English one too). On my PC, the locpak is in E:\MSFS\Official\OneStore\fs-base\en-US.locPak

Sorry one other thing I noticed is some odd naming since the rebuild.  But maybe a FS issue?
Doesn't look like I can paste the image but the info panel shows (also this would be nice if we could copy the text).

For Cardiff Airport the info panel shows:

QuoteEGFF  -TT:AIRPORTEK.EGFF.name - TT:AIRPORTEK.EGFF.city
TT:AIRPORTEK.EGFF.country

Then all other info looks correct

One thing to add, I can see a difference in the resulting Air Space.
ie, now the area's are not shaded where as they used to be.

I wonder if that points to the issue?

Well that fixed, but how odd.
It's one of the first things I tried to do to fix it, but it didn't make a change.

Oh well, I'm not going to question that any further.

Thanks,
