cwchar trouble

[Yoooooo]

Let's just move on the subject. My codeblocks version is 16.01, my win is 8.1 with 64-bit operating system. I've just installed the current version of codeblocks ( but still i hadn't uninstalled the last version which was older, i don't remember what version though ) and now this is what i'm told as an error i think (http://i.imgur.com/eK3OLFR.png --> screenshot).
I'm kinda embarassed, it's the first time when this shows to me and i have no idea where the trouble is. Please, can you help me? I really need my codeblocks fixed. Thanks!
