I just now experienced a similar situation. I have been out of town for over a week, have logged into LW (4.8.1 Pro) with a Turbocharge connection, and any attempt to dl one, then two and now three audio files has resulted in the "queued" response to each one.
I have never seen this in three years of using LW except when trying to dl too many files. I have the limit set to 12 and 100% bandwidth use.
The last time LW was used a couple weeks ago, things were fine.
Any ideas?
