Thanks Mates, Ansley for your feedbacks

reg. 400mb limit:
I do post with this service since about 6months now and i know how to use it

I have not set any link as "Premium only" there on my account
I got some "complaints" on my site last sunday night (CET), regarding filesize, i checked it with my free test account (No fraud activities intended!) and the guys were right: i couldn't load a 350mb file.
There was the window "u need to upgrade your account..."
Now it works again. Thanks
Stability is very important these days
