MIght I suggest that you try a full install. I had problems initially with LL Live on my fujitsu siemens Amilo lap tops. . When I did a full install, I then went through the generic options menu/settings/keyboard AND menu/settings/keyboardinputmethods one by one, rebooting after each change until I found the right combination. I realise that this could/will be time consuming but should eventually be rewarding. When you find the right combination, could you please post it on the forum for others' use later on.
Also check language support is OK
If you go to Menu > All and select Language Support
