Lastviewstab is a 3rd party plugin and should receive support from its developer. Additionally the latest is 0.2.9 stable.
The profilebook you have is for CB 1.0, You're using CB 1.2. The latest profilebook is available to document subscribers, which will function properly on CB 1.2 in addition to that there are many new features.
Correction: Lastviewstab is a CB release, but at the moment I believe it requires legacy.
