Cortex command came up with an error during the startup, saying something about could not find some file.
So I uninstaled it and the installed CC19 to register again, but it said to many key registrations (something like that)
So, Im stuck, I can't unregister because its not registerd, and I can register because the key dont work.
WTF do I do?

Post the error here and email data (support@datarealms.com) for your key to be reset.

I dont know the missing file error, I think it was caused by a custom scene which used a mod.
The key error was about the key being already registered - I can only register on B19, so I have to downgrade to register, then upgrade to play. And when it goes wrong I do that all over again. I dont see why B20 does not connect to the key server, but B19 does.

Then send an email to support@datarealms.com, asking to unregister your key. Then, in that same email, describe your problem, namely that you are unable to register with Build 20.

I already sent one, but without the B20 error, they havnt got back to me yet...

Also, what are you meant to do if files and mods dont work?

Either fix it, or delete the mod.

..fix with what?

With EDITING SKILL.

Open the .inis in Notepad. All mod files are plain UTF-8 encoding. If you want to fix it, learn to mod.

The alternative is deleting it, and waiting for the creator to update if you *really* want to use it.

Hmmm
I did have a look through the files to the error line numbers.
I check the file the line linked to, played the game, failed again...
So now on, I just keep installing over the files...That shouldnt do no harm right?

What mod is it that's giving you problems?

Biglands
That large cannon mod

But I think it is when I use them in the scene editor.
