@ Kojak , not everyone is able to code in c++ and this is a Gamestudio Forum , we all want to use the Acknex engine for our games and c-script is the language for that . Of course its better to use a dll in c++ to get better results but not everyone can do that. Feel free to show an example how to use c++ to make a better result.

@ PrenceOfDarkness , thanks i am sure its possible to improve this script with including the users Name and adress and stuff , but the code would be more complex for doing that. For generating a key only once you can save every generated key to a file and let the engine compare all generated keys with the new one. in my example i use 500 in the limit_maximum file , just increase it for more complex keys , but dont change that number after releasing the game . Use always the same number in one game or change the chars-txt file for other games.

@ bot190 , sounds like you need a wait(1) somewhere , dosent checked it yet because its running fine for me and the others. You can edit the script for your needs , if you have problems to get it working , let me know and i will try to help.
