launcher issues

I was Playing my game until it froze so i got out of it. when i tried to start the game up again from the launcher it would not start. i clicked the play button and the game didnt start but it was in the task manager

When I try to open MBII launcher a box appears and says ''Application is already running...'' Please help me :(

Like the title suggest my Launcher is running but i cannot access it and for some reason i cannot disable it in task manager. This is the first time this has happened ive successfully played it for the past week. Any help will be fine, Thank you :)

I just downloaded the launcher and placed it in the gamedata folder and when I try to run it, it says "Not enough space on hard drive!" The game requires 3GB. My harddrive has 501 free, which is more than enough. Any help would be appreciated
