Hi gimmeagig,
Sounds like you now have a 64-bit operating system. There have been a large number of posts in this forum about how Sound Canvas will only work on 32-bit systems (including Win 7, 32-bit). Here's a some information about it ...
http://www.pgmusic.com/rolandvsc.requirements.htmGiven that you have BIAB version 2008.5, the best solution would be to consider buying Coyote Forte. The link below will give you some information on this.
http://www.pgmusic.com/coyotefortedxi.htmThe current version of BIAB ships with Coyote Wave Table; this functions similarly to Sound Canvas. Unfortunately, my understanding is that the above wave table does not work with 2008.5. (If you dropped PG Music a quick email, they'd soon tell you.)
Hope this helps,
Noel
