it wont let me run the game, it says that there is no UnityPlayer.dll. and it says it can be fixed reinstaling the program and i alredy did and it says the same thin, so, what should i do?
Have you tried completely re-downloading the .rar and/or using a different decompression program?
Whenever WinRAR has failed, both Bandizip and 7zip have always succeeded. In fact, I stopped bothering with WinRAR several years ago, since Bandizip and 7zip are both free anyway.
