I uninstalled LiveCycle from my windows machine and restarted it. Now when I try to start CQ6 I get this error when trying to load up any page. Even http://localhost:4502

Problem accessing /. Reason:

    AuthenticationSupport service missing. Cannot authenticate request.

I see the following in my error.log

01.05.2015 22:27:24.577 *ERROR* [FelixStartLevel] com.adobe.granite.repository.impl.SlingRepositoryManager start: Uncaught Throwable trying to access Repository, calling stopRepository() java.lang.IllegalStateException: Segment 55c759a2-2ced-4d9e-af48-45209e6aa829 not found at org.apache.jackrabbit.oak.plugins.segment.file.FileStore.readSegment(FileStore.java:541) at org.apache.jackrabbit.oak.plugins.segment.SegmentTracker.getSegment(SegmentTracker.java:106) at org.apache.jackrabbit.oak.plugins.segment.SegmentId.getSegment(SegmentId.java:97) at org.apache.jackrabbit.oak.plugins.segment.Record.getSegment(Record.java:68) at org.apache.jackrabbit.oak.plugins.segment.MapRecord.getEntry(MapRecord.java:138) at org.apache.jackrabbit.oak.plugins.segment.MapRecord.getEntry(MapRecord.java:170) at org.apache.jackrabbit.oak.plugins.segment.SegmentNodeState.hasChildNode(SegmentNodeState.java:326)

How can I resolve this? I can't even access any pages!
