Can't encrypt text

[frgt10cs]

I try to encrypt message
var x = cryptico.encrypt("mytext",cryptico.publicKeyString(staticKeys.RSA));
where staticKeys.RSA is RSAKey
And i get error:

aes.js:131 Uncaught TypeError: Cannot read property '177' of undefined
at Object.my.MixColumns (aes.js:131)
at Object.my.Encrypt (aes.js:86)
at Object.my.encryptAESCBC (cryptico.js:3395)
at Object.my.encrypt (cryptico.js:3493)
at HTMLButtonElement.CreateKeysAsker.generator.onclick (script.js:162)

my.Encrypt @ aes.js:86
my.encryptAESCBC @ cryptico.js:3395
my.encrypt @ cryptico.js:3493

What's wrong?
