Mal.
ok back had my treats lol.
1..a question ...does asio biab only crash when cubase is open ? is biab asio ok if no other app is open ?
2..we need a pic of your asio settings in bb plz.
ie the drivers selected in biab.in preferences.
per pipes example pic.
3. in that win display pic it dont tell whole story.
clik on 'manage sound devices' and in the dialog that comes up make sure in properties in advanced tab exclusive mode is unticked.
PLEASE READ THIS>>>>

if not already done mal spend a day googling lots of articles on the net and you tube re optimising a windows pc for music production. save the articles.
i cant cover every topic. this stuff mate aint trivial ,
and if people ignore , often leads to problems.
try also manufacturers of sound interfaces web sites. theres a ton of info out there , also on pg here.
ie articles and vids etc.
