Answer 1

The config.ini file should specify org.eclipse.core.runtime@start in the osgi.bundles property. Here is the default osgi.bundles property, maybe it was (accidently) changed during some upgrade:

osgi.bundles=org.eclipse.equinox.common@2:start,org.eclipse.update.configurator@3:start,org.eclipse.core.runtime@start

Answer 2

try running it from the Command Line as:

 >eclipse -clean

Or, you could run it using java instead of the default javaw, here:

 >eclipse -vm c:\jdks\java_1.5\jre\bin\java.exe
