Xigncode is Dekaron’s anti-cheat measure, which keeps the game from loading if it detects suspicious programs on your system. 

Try running the game after attempting each of the following:

1. Run a virus scanner and then close all third-party software.

2. Close any programs you aren't actively using. (including disabling browser extensions).

3. Run CCleaner.

4. Temporarily disable your anti-virus system and firewall and see if the error code goes away.

5. Delete the xigncode.log (if it exists).

6. Delete all files in the temp files folder ( to do this, open "Run" window, type %temp%, click okay and you will get your temp files folder).

7. Restart your computer.

8. Open up task manager and close whatever you do not need.

9. Run the game as administrator.
