"Cannot receive Extensions, why?"

I am new to RapidMiner. Once I try to start updating RapidMiner 5.1.014, it gives following message:


                        Cannot contact update server http://rapidupdate.de.80/UpdateServer. Please check your Internet Connection.
Please help.

Do you connect through any proxy server or firewall that could be blocking it? 

Best,
JEdward.
