Problem with Bazille- no sound

[rockmachine]

Hey guys,

I have no idea of what has happened or going on presently. Yesterday, I started a new piece in Cubase 7 after I spent ages developing a really great sound in Bazille. I liked it so much I got worried about losing it, so at the top window of Bazille, to the right of the program name- in the black background window, not the name at the top middle-I saved it under a name in a folder of my own patches. Everything worked fine then, and I even loaded and saved another one after messing about with the one I already liked, and also was able to then get back to my original just by clicking on the original named patch. Now today, i opened the song file and there is no sound at all even though there is action within the oscilloscope. I can play the synth using MIDI, see action again, but still no sound. I then loaded a factory sound and they work normally too.Does anyone know what is going on, or is this just another stupid thing in Cubase or something to do with VST3? Thanks in advance. By the way, I have an ImposCar 2 in it too and it's working fine.

Now, weird addendum: I was dicking around with the file loading other synths, etcetera, and after I loaded a Zebra, I thought I would clock the "revert" tab and boom! Bazille was good to go with my patch. So i have no idea what happened. I also loaded a Zebralette and was able to load patches I designed and saved in my own folders in both Zebra and Zebralette. I am still trying to figure out other stuff to do with the differences in VST 2 and 3 and how what you have to do with your old fxb, patches to make them work in VST 3. I can't figure it out from the Cubase manual, so if any of you guys know the fast route, let me know. I don;t want my all of my old fxb patches coverted either as i stil use Cubase 3 some of the time. I realize you just have to make a duplicate folder before converting, but still not sure of the actual coversion process.
