My profile isn't being updated with loved tracks or scrobbles

Hi, a day or two ago my profile just stopped scrobbling tracks. i know for sure that my client is receiving whatever winamp sends it, it has proper access to the internet, the server status page says last.fm is working perfectly.

any tracks i play, new tracks i add, music love adds... nothing appears on my profile anymore, the last time i listened to that 'oh boy' song from cam'ron is a couple of days ago...

any ideas?

i had the same problem before and the only solution i can get was format my pc, but i have the problem again, please tell me if you find any solution that isn't format :p
