incredibly annoying and totally false"you have downloaded more than 50MB..."

can someone explain please why i CANNOT d/l anything from WinCustomize - i keep getting these msgs about how i have "already" d/l'd 50MBs worth of skins - which is completely untrue... i doubt if i have d/l'd more than 15MB over the course of an entire YEAR! this is a 'public machine' - in an internet cafe - so i suppose someone else from this IP could have d/l'd a bunch of stuff... in fact now that i think about it... since all 10-12 machines here actually share the same (public) IP address, if that is how WC is tracking d/l's than perhaps that is the problem... so then, how do i fix it? i notice that everytime i come to the WC website, i am apparently 'logged in' even tho i dont have an account! and the logoff button doesnt work - doesnt do anything at all in fact.
hm, frustrating. nothing like being penalized for someone else's greed!
any suggestions would be greatly appreciated.

PS the account i am posting here under is not my own, so email sent to that address will not reach me (at least not directly i suppose) i'll just have to keep checking the boards for an answer...
