Grassroots research: do you ever have the problem with Vegas Pro that you click on record, the tracking starts and then freezes almost immediately, leaving you stranded in mid-launch?
I was using Vegas w/ a Lexicon Core 2 and it did that!AAAAARRRRRGGGGG!
I spoke with a tech at SF, and he said that it had something to do with the drivers not being updated. Call SF and they should give you the skinny on how to fix it.
