Provisioning exception

[reprogrammer]

When I installed CodingSpectator v1.0.0.201101151513 on a fresh instance of Eclipse Helios SR1, I got the following exception in the error log of Eclipse.

org.eclipse.equinox.p2.core.ProvisionException: Communication with repository at http://download.eclipse.org/technology/epp/packages/helios/R/ failed.

I looked up the URL http://download.eclipse.org/technology/epp/packages/helios/R/ reported in the exception. It looks like that this URL has been archived. But, I don't understand why it might have got archived because Eclipse Helios SR2 hasn't arrived yet. It could've been just a timeout due to my slow Internet connection.
