I got the advise from PGMusic support to delete the ini files from both BIAB and RB so i did and then i uninstalled the UA-700 driver, rebooted, installed the UA-700 driver and rebooted again. They advised me to plug off my ROland EXR-5 keyboard so i did.

When I started BIAB I noticed when the Audio Setup dialog appeared and below the dialog I noticed there was a <yes>. near the sample rate 44.1 where i had seen <no>. previously, despite the hardware setting of 44.1 (advance) on the UA-700 control panel!
Perhaps the keyboard as Mini-input caused the sample rate change to an illegal setting causing the violation error?
