Someone suggested I hold down the 2 and 3 keys when I restart so that the system will revert back to 32 bit (whatever that means). It worked after I did that. I just need to remember to hold it down whenever I turn the computer on. Or else, I'll have to restart to access the VPN.I'm not sure what gets affected when you do this though. But, I seem to be able to carry on very well.
