fake authentication help

[tomahawk$7]

Hey guy wondering if anyone can help me here. this is a really tough access point and i have noticed a few strange things while trying to do a fake authentication.

i tried to
aireplay-ng -1 0 -e --bssid -a 11:22:33:33:33:00 -h 00:11:22:33:44:55
the first night i tried this i cant remember exatly what it said but the screen went to packets read and started counting up. Also in aerodump the auth went to ska shared key authentication.

So i assumed that this access point that i had cracked once before that was just wep now had SKA so i followed the guide on aircracks site for SkA..
the probelm i had there was it wouldnt load madwifi drivers. Im using BT3 so not sure if they have the madifi drivers on here..

So i gave up that night and read some more tutorials tried a few other things.
Next time i open aerodump to try again it says Auth is open not SKA.
So i tried
aireplay-ng -1 0 -e --bssid -a 11:22:33:33:33:00 -h 00:11:22:33:44:55

I get
Sending authentication request
authentication request successful
sending association request

and it just says that over and over and over..

i tried a few differnt variations but come up with the same thing..

is it possible this is still SKA and its just showing it as Open still because i cannot accoiciate. but then i wonder because first time i tried it said it was SKA and started collecting packets..
Im very lost here any help would be great..

also i have cracked this persons AP a few times they seem to change there password every so often and now they have hidden there ssid..
