Surprise...

After couldn't sleep well last night 'cause I try to reinstall/repair my VB.NET installation, which end up with the same error! :(
Today, I turn on my computer, and wow, surprise, my profile back to normal again!!
So, what did I do last night?? Really wasting my time, if only I knew all I got to do is just log off and login again, so simple :p
But, dunno if that problem came up again and can't be fixed, so I better back up my system now :p
