In April 2013 I used MultiPDFSplitter1.4 Setup and also BatchPDFMerger-Setup27.

I purchased keys. After not using for a while and just tried to add my Keys I get a 'invalid details' error? So I can't remove watermarks, etc. on split PDFs. Why are my keys invalid?

It's possible that your keys have been discontinued or expired. The only thing you can do is to contact the developer of these applications because he is the one who can issue you a new key. Use the following contact methods to get in touch with the developers of the applications:

Multi PDF Splitter:

Batch PDF Merger:

I see the applications are developed by the same developer. Contact using one link and mentioned about the second application as well.
