2010 All Star Uniforms cheat not working.

I literally typed otnresla correctly but it still keeps saying its an invalid code. How do I unlock the 2010 All Star jerseys?

If you're talking about the PC version, it might have been a console-only code. It's only been the last few years since the PC version has been receiving the same support and content updates as the console releases.

Yeah true. But here is the weird thing. None of the uniform cheats are working for some reason. :/

It'd be the same reason. The content was pushed through for the console versions, and not the PC version.
