Can anyone else log into their DMM account?

[jinux]

I have been trying to purchase videos from DMM but every time I enter my username and password it either redirects me to the log in screen again or says that I've tried to execute an illegal action (or something similar...it's in Japanese and my Japanese isn't perfect). I know that I'm using the correct log in information because if I enter in the wrong password it will tell me.
Anyway, just wondering if anyone else has had a similar experience and if so, how did you fix it? Thanks.

where are you logging in from? a change in their policy maybe? also things like noscript or ghostery can interfere with login sometimes...but those things would be more obvious.
