Update not working

[Cavou]

I have the full vesion of creeper world 0.380 and want to update it.I download the update but it doesn't update it.
It says this:You must install the full game and run it at least once before installing a patch.  Once you have done this, then install the patch.  You can install the full game over this version, run it, enter your license key, then reinstall this patch.
I have the full version and played it more than once.But it still says that.

HELP ???

Are you running on Windows or Mac?

It sounds like your key is not recognized.

I unfortunately don't know the corresponding procedure for Mac, but for Windows do this.

Open Windows Explorer. Note: Not Internet Explorer, but the file Explorer.

In the address bar type  %appdata%

You will see a folder named: CreeperWorld

Verify that there is a file in this folder named: keyData

Post back on whether that file is there.

The instructions I gave you will work on Windows XP, Vista and 7.

I found it but I coudn't find the key folder

That means you never provided the key. Just as the message says.

Uninstall the game (Your saved data will not be lost). Install it again, start it up, it will ask for the key, give it, and then install the upgrade.

Edit: I will be in chat for a short while if you need more help.
