Won't let me change modes

Hi, hoping someone can help. I just downloaded the trial for Millennium 2 (after having bought A New Hope on bigfish games and really enjoying it) but when I import my game save file, it won't let me change the mode of play. I played through the first game in easy mode but felt there was quite a bit I missed out on and wanted to try Millennium 2 in normal mode.
Only, when I select "normal" at the start of the game, my characters all still have "EASY" next to their names. Thought maybe I had made a mistake with my save file somehow, so downloaded the one kindly provided by Dee on here, but the same thing happened (although that save file leaves me stuck in "HARD" mode, and don't really want to jump straight from easy mode to hard mode).
I read a post where someone said it was possible to change the mode, so I'm a little stumped as to why it isn't working for me. If anyone can shed any light on this, I'd really appreciate it.
BTW Indy, if you read this, I LOVE your games :-) There's always so much to do and explore, it's impossible to get bored, ever. Don't know how you do it, but your hard work is really appreciated (and if it's of any interest to you, I discovered your games on BigFish)
