Are you experiencing computer problems like reboots, blue screen or system crashes intermittantly or while using any other program?

Have you tried the VST and VSTi with multiple (different) song files or with one song file?

If you are experiencing issues as I first described you may have a hardware issue such as hard drive needs to be defragged, clogged fan causing overheating, power supply starting to go bad, loose connection, ribbon cabling insulation shorting against the chassis or the thermal paste on the cpu has evaporated. A loose screw can cause weird issues too. If the only time you have an issue is when you use one of the plug-ins inside BIAB or RealBand it's likely not a hardware issue.

If you haven't done so try using the effects with multiple song files. It's possible your song may have become corrupted from the crashes.
