That did the trick!

I'll give 50 a try and see what happens...

Why do I feel uneasy when you say that it is really bad? [;^)
Everything else appears to be working fine at this time... And I'm
going to back-up again today just in case.

I can reproduce this error easily by attempting to download a large
MP3. I've created another large MP3 to see if it is just a problem
with the first track. This one is 23.2MB and it does the same thing.
So far, the largest MP3 that has worked has been 4.3MB. I'll see about
trying different sized ones until I find the limit. Either way, I'd be
happy to do some testing for you!
Thanks!
