Blizzard Sorceress won't attack

[Huginn]

I set up a blizzard sorceress to run Mephisto. My main skill is on F1, teleport on F4, and my buffs on F5 and F6. It casts the buffs, teleports to the boss, then stands there doing nothing, and says 'Waiting to reach Mephisto - 12'. It stands there for about 10 secs while my mercenary dies, then exits the game. I also tried Andariel, it teleported there and casted my left click attack skill for a while, then chickened. It never casts Blizzard. How do I fix this? If I can get it working before my trial ends, I'll pay for a subscription.
