Last.fm Scrobbler doesn't scrobble after hibernation

[SyncMusic]

The Last.fm Scrobbler (1.0.2.29) doesn't Scrobble any tracks after I wake my PC up after Suspend to Disk. The Log of the Scrobbler also shows no activity after the PC went into Hibernation mode for the first time. If you close mediamonkey (4.0.2.1642) and restart it, the Scrobbler works fine again.
Update:
Suspend to Ram doesn't cause this problem, only Suspend to Disk seems to cause this.
I'm using Win 7 x64 if that helps

I have the same problem but it also happens when I hibernate, also using Win7 x64 and MM4

I've got the same problem as mentioned above. Are there any solutions?
