the hyperlink in my original post won't work - its designed for another version of BIAB. but, found the amplitube 3 installer in the bb directory and ran it just to make sure. no difference in RB. still no presets.

tried the amplitube demos in BIAB and they all load the required preset for the track but again the browser button says 'can't open the presets database' or similar. so i've got a fully functional amplitube 3 but can't point it to the right place to find the presets in either BIAB or RB.
