PDF Creator version 2

I used the previous version successfully to produce PDF documents with 128 bit password protection. The document size was unchanged (generally around a Gb)

When I saw version 2 announced, I upgraded, but the resulting documents were much larger , around 10 Gb, and no longer be to be attached to my emails.

I have reinstalled the older version. Is that likely to remain available?

Is there some setting that I missed, that caused the inflation in file size?
