There are two ways to enter a password: Copy/Paste and Type It yourself. Only after trying both of these options you can say for sure that you have the wrong password.

BUT, sometimes it's possible for WinRar to give the wrong password error because there's a corrupt file, so check if that is the case. WinRar Corrupt Files (CRC Error!) FAQ entry here: http://www.rslinks.org/node/2404

DO NOT automatically assume that if WinRAR tells you that a password that you've entered is incorrect that WinRAR is right.
