Well, it works here.  Using 9.21.1.  I think it is using passive FTP, but I will have to confirm that.
Here are some things to try:
1. Go to a DOS command prompt.  Type
ping wirelessftp.fcc.gov 
You will get a timeout.  But note the IP address.  Is it an IPV4 address like 35.168.142.79, or is it a longer IPV6 address?
2. Can you download from 
ftp://wirelessftp.fcc.go...uls/complete/l_amat.zip in your browser? 
3. Try turning off the Windows firewall.
Note that if # 2 works, you can import the file into LOGic.  Copy l_amat.zip to c:\program files (x86)\logic\tmp
 Click on the PROCESS tab in LOGic, and click PROCESS.
Let me know.
Happy new year,
