I am finishing up my game and I have a string called "str_version" to show the version number on the splash screen.
That is the only place this string is used in the whole game.

If I change the content of the string to "Version 1.0" the game will not run. It crashes on startup.

If I have any other string in there it works fine.

Am I going crazy?

It s a global String and / or dynamic String?
"Version 1.0" is writen by? Where do you read the number? Are you tryed any other number?

Have you tryed to seperate your startup code?
Have you tryed a seperate test project?
