When log shows "Last.FM: Submit OK" its actual format is "Last.FM: Submit <Last.fm submit server Reply>" so in that case "OK" means that last.fm accepted Plugin submission and it is processed by last.fm site.
[quote="http://www.last.fm/api/submissions"]OK
This indicates that the submission request was accepted for processing. It does not mean that the submission was valid, but only that the authentication and the form of the submission was validated. The client should remove the submitted track(s) from its queue.[/quote]

Unfortunately unless we are able to replicate same behavior and Submit replies with OK there is no way to see if last.fm included it in your profile or not. As no changes were made on our part and your profile started to update this indicate issue on their part :(

I'm glad it is working for you now.

After not working for weeks, all of the sudden it's working again?

Magical...

Hey all,
I'm having issues with the last.fm addon. I've tried with 2 MM versions (right now I'm using 3.2.0.1294), and have installed the newest last.fm plugin (ends in .21? IIRC)
I have it all setup, password/username entered, etc. I have it set up to both scrobble tunes as well as show my "now playing" on last.fm. It also shows a "green" taskbar icon in MM.
It does successfully show the track I currently have playing on last.fm, but it is NOT scrobbling the tracks when they are finished. Looking at the log, it seems like all is well, it creates a handshake session, and it says it's successfully scrobbling the tracks:

And my last.fm:
[i]Recently Listened Tracks
Listening now using MediaMonkey
The Wooden Sky – When We Were Young Listening now

Sufjan Stevens – The Seer's Tower 30 Nov 11:55pm[/i]

The Sufjan is the "newest" scrobbled track, and this is from my other computer. The now playing is from this computer.

Any help is greatly appreciated, thanks!
