Eclipse Luna SR 2 (4.4.2)

Dragging the Install Button from http://eclipse-cs.sourceforge.net/#!/ to Eclipse

New window, i select Checkstyle Plugin 6.4.0 and confirm. I confirm the Licenses. I press finish.

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust, operand=, action=).
Error reading signed content.
C:\eclipse\plugins\net.sf.eclipsecs.branding_6.4.0.201503042206.jar (Das System kann die angegebene Datei nicht finden)

I translate the last sentence: The system is not able to find the mentioned file.

Bug? Misconfiguration?

TIA
Chris
