I have one problem with last.fm. I have used other music players (exaile for example) and it have worked, but now, when i use amarok, my last.fm profile aren't updated correctly. My "recently played tracks" är updated, but the "overall top tracks" are not affected, is it something to do with amarok or is it last.fm that is wrong?

I also use last.fm with Amarok (1.4.3). Everything updates correctly. Overall top tracks doesn't update very frequently, I notice. Monthly, maybe?

Maybe.

Since your tracks get scrobbled, it's a "problem" of last.fm, not of amarok.
Perhaps ask at their forums?
