Problems with scrobbler plugin

[arendm]

I'm using the scrobbler plugin with xmms to drop data at Last-FM. It works allright if i play my songs directly but if i play them via Ubuntucenter i get this message on the Last_FM webpage:

"Some tracks you submitted have not been added to your profile for the following reason:
Spam protection triggered: You submitted a track dated earlier than your last submission."

Can anyone tell me please what is wrong here?

Check the date in your box.

I'm sorry Ptero, but i don't know what you mean. Could you be more specific, please?

I mean the date displayed in whatever clock program you can run (the clock applet, xclock, the time command, etc).
