I've had a few errors recently:
"...not the correct file or was garbled"
"Starting result for wu using setiathome version 4.03" ( I've got 4.05 
loaded)
Checksum or signature error for wu
Giving up on download wu
Plus a few more. There are multiple incidents with the same errors.
Are we back to having serious problems with whatever we were having problems 
with a few weeks ago?
