I installed Zenpage. Changed my Gallery page to Zen's default theme, but not the albums, yet. Went to Plugins (Admin) and didn't see it listed. Logged out and back in. The theme for Gallery index changed. In Admin tooldbox went to Admin. Looked for Zenpage plugin. Didn't see it.

Looked in Options and saw nothing relating to Zenpage.

If you did not see zenpage in on the plugins page then you did not get the zenpage files properly copied from the distribution to the zp-core/plugins folder.

Okay, reinstalled, saw the plugin, saw the tab. Clicked it and got error:

Zenphoto Error
MySQL Query ( SELECT id, cat_name, cat_link, hitcounter, permalink FROM zp_zenpage_news_categories ORDER by cat_name ) failed. Error: Table 'rbcphotos.zp_zenpage_news_categories' doesn't exist

You need to manually run the zenpage setup. ..zp-core/plugins/zenpage/setup.php. For some reason it did not automatically run.

The setup didn't run automatically for me either. Maybe it should be mentioned in the installation.html file.

It should actually and has been corrected in the svn version btw. But I will add it.
