this problem has also happened to me. I changed the system's language to English, then AI2Offline works normally. try to do so.
finally it worked thanks mate.
I used the installer version, but i have this error: HTTP ERROR 500 java.lang.IllegalArgumentException: RFC6265 Cookie values characters restricted to US-ASCII: 0x661 URI: /_ah/login STATUS: 500 MESSAGE: java.lang.IllegalArgumentException: RFC6265 Cookie values characters restricted to US-ASCII: 0x661 SERVLET: _ah_login CAUSED BY: java.lang.IllegalArgumentException: RFC6265 Cookie values characters restricted to US-ASCII: 0x661

I see some strange characters in the DevServer console, is this Normal or what?
