[plt-scheme] Planet SchemeUnit down?

Hi,

I have problems using SchemeUnit from Planet in v299.105. It worked in 
version v.299.104, but after I've removed the old Planet directory  my 
program simply hangs indefinitely while it tries to download the new 
code. I have also tentatively switched Firewall and packet filters off, 
but that didn't help. I've also issued planet -U from the command line 
but that didn't help either.

Is the server down or might that be an installation problem on my 
machine running Mac OS 10.3.9?

Best regards,

Erich
