I've tried to install again the 2.3.2 this morning and now it works... maybe with the old dw preference restored from backup (with DB 2.3.1) fixed something in the installer, I don't know what exactly happened but now I've 2.3.2 installed.
A last question, where is possible to see the version number of DataBridge installed on Dreamweaver (on WebAssist "Preferences" or "Preset Manager" I don't see nothing)?
