Trouble with Last.fm playcount sync

[Babydoll32]

Hi,
I've the problem, that MB won't sync playcounts back from Last.fm.
The stats plugin works and shows correctly, but MB won't. Not automatically, not manually.
I can also click the song in stats view and it jumps correct to song in library.
I don't know, where's the problem with playcount

The problem might be with last.fm eg. there might be a delay of some time before the data shows up in the API MB uses.
Otherwise the playcount cache can get out of synch with last.fm so try deleting:
C:\Users\<your id>\AppData\Roaming\MusicBee\LastFmPlayCountCache.dat
The first re-synch will take a long time

Hi, Steven.
Thx for your fast answer. Tried Cache delete, but didn't work. Other songs get's updatet, but this one and another one I tested won't 
Can it be the reason, cause it's not an official release? It was a live performence within a TV show, which never official released.
But I wonder, why it's getting scrobbled and why it appear in the stats-plugin??

After spending some f### hours, searching failure in tagging, MB whatever, I think I found out the problem. It's last.fm itself. In profile settings is an option for spelling correction, by default turned on.
Disabling seems to solve it.
