Before going any further, follow the advice printed on the front cover of your copy of The Hitchhiker's Guide to the Galaxy: Don't Panic.

Next, read "SECTION GUIDELINES - PLEASE READ BEFORE POSTING HERE" (it's in all caps for a reason).

And here's a very detailed post on troubleshooting.

If you provide sufficient information, it might (or might not) be possible for others to determine what's wrong and help you to fix it. If you don't provide necessary info, it's almost certain that nobody will be able to randomly guess the solution to a problem that you've not described meaningfully.

Think about it. You phone an auto mechanic and say, "My car doesn't work! It has tires and a radio antenna but it won't run!" Three frustrating (and in the real world, expensive since mechanics gotta be paid) hours later the mechanic says, "When I asked earlier, you said it's an old car with a gasoline engine. How much fuel is in the tank?"

"… um. Fuel???"

Provide the info the mechanic needs right up front. Save her*, and you, a lot of time and effort. Good luck!
* nope, different mechanic; this one doesn't use a pipe wrench

The "One file failed to validate" is not a problem, it happens to lots of users (including me) and does not in any way mean you can't play the game. Just ignore the error and launch it as normal.
