(I've looked for another (english) thread for this, but it doesn't seem to be very current, or even there. If I missed it I apologize.)

"Mediafire plugin error (out of date)"

Do you need a log from me for this?

Thanks!

EDIT BY PSP:
Because MF changes their page after every jd update the plugin will likely be always defect.
I put this thread on top that its easier to find for new users.
