Can't load modpack

[Robandoban]

When I try to play the modpack it loads up to a certain point and then says that it can't delete codechickenlib so it won't play. when I try and manually go to the folder and delete it, it says it is currently running in java and can't be deleted. What do I do?

I have the same problem, it says check your system settings and I get really confused!
