Hi,
I would strongly suggest that you ask at the official forum he

Also, while version 3.4 is the official production release, it is
really very old. Try the current beta, which despite the name is
effectively the production release. You can download that he

The latest version, 1682, is solid, and has several fixes over the 3.4
version. Generally, when you have a problem, one of the first
suggestions is to upgrade to the latest version.
