As a newbie, I've played most of the GCIII Crusade Campaign Scenarios, but even at Beginner Mode, I find it hard to complete the games. 

I understand these games have compatibility issues with Crusade; maybe that's part of it. And maybe it's the way I play - it prolly would take me another 100 turns to to finish off the enemy and win the game. I'm just ready to move on to the next game. But leaving the previous game as is, the next Locked Game is still locked.

I need something to bypass this and be able to play the Locked Games. Is there another way to unlock the Locked Games, so I can play them? I'm done with the previous games. I really don't want to have to start over with the unlocked games that I've already played.
