Probléme avec le format stings et le JIT.

Salut j'ai un probléme sur mon ordinateur quand je veux lancer un jeu, et me lance un rapport d'erreur me disant: an unhandled exeption has occurred in your application if you click continue the application will ignore this error and attempt to continue. If you click Quit, the application will be shut down immediately.

Input strings was not in a correct format.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.


Voila ce qui me lance lorsque j'essaye de le lancer.

Merci d'avance pour votre aide.
