I don't have P2014, but if it uses the same Flash based indexing system as Pro2010, then the issue could be a Flash problem, not just a Poser update issue. Flash updates very frequently and I have seen the issue with dropped image indexes happen with my version of Poser after a major Flash update.

You can try uninstalling/reinstalling Flash, followed by your Poser update. You could also try to get your system to index your runtime directory, but that would probably take forever if yours is as big as mine. :)

I solved my issue with a reinstall of Flash and Poser, which cleared out all the old Flash conflicts/whatever that was causing my particular indexing issues.
