Eclipse: MarketplaceDiscoveryStrategy failed with an error

Question

I've just installed Eclipse Helios version 3.6.1 on my Windows 7 64 bits machine. But, when I want to open Eclipse MarketPlace I get this error:

MarketplaceDiscoveryStrategy failed with an error.

Unable to read repository at 
http://marketplace.eclipse.org/api/p?product=org.eclipse.epp.package.jee.product&os=win32&runtime.version=3.6.0.v20100505&client=org.eclipse.epp.mpc.core&java.version=1.7.0_07&product.version=1.3.2.20110218-0812&ws=win32.
