@myg: If you are still having trouble, try:
1) Reinstall from DVD as "upgrade". That might reinstall your BFE. Repair Install
2) Repair Computer - from Boot CD or by repeatedly pressing F8 on boot
3) Start CMD (Accessories, Right-Click, Run as Admin) and run sfc /scannow - that might repair/replace BFE
Or maybe logicearth has you sorted out on a different thread.
