Hey, im new to the forums, just signed up then

Definately a sweet site - onto my problem.
Ive followed the guide - Im an elementalist level 21 - Im tryin to use snow hazard as my no cool down skill, with Grioli as the skill im TRYING to use (I have the fire dude so i dont need my Griolo anymore)
My problem is! - As soon as i press the "On" button and maximise arch lord, my whole game goes all glitched out and ****. Im not sure what the problem is but all i know is it ******* me off lol.
Can anyone help me out with this problem?
And also - The one time i got into the game and it WASNT glitching out, i tried casting my Grioli (AKA snow hazard) but nothing would cast. I went back and casted snow hazard by actually casting snow hazard and it casted fine and did damage...Im not quite sure what the problem is - My game shouldn't be glitching out cos my comp can definately handle this game so yea, any help anybody?
EDIT: Ok well the glitching out seems to have stopped - It must have just been that area in the game that i was testing the no CD in. I still have the problem of when i try to cast my Grioli its just not casting snow hazard... It wont cast anything - I target a monster, click Grioli and nothing happens...
Actually, that brings me to another question - Could the reason its not working be the fact that Grioli is a summon and cannot be cast on monsters? I dont have any other attacks to swap around and test it out with so i cant really test it... Anyone else with a Moonelf wanna try this out for me?
Thanks,
Matt
