Sleep? What's that. My girlfriend is a slave driver.
Try to activate the Firewall again.
If it errors, what does the error say.
You can use this precess to show us the error message.
To attach an Error message, left click the mouse on your Desktop.
Press <Ctrl> C
That makes a copy of your Desktop.
Open the Paint program.
Press <Ctrl> V
This will paste the image created above into the Paint Program.
Do a
Save as of the image to your Desktop. Call it
Image1.
Now if you mess up

, you can retrieve a fresh copy from
Image1 
.
Cut off the excess of the image in the Paint program so only the Error message appears.
Once you are happy with the picture, do a
Save as to the Desktop. Call it
Image2.
Now open the
Image2 to verify that it looks like you want it to. Remember, you can always start over with
Image1. So don't delete
Image1 until this problem is fixed. OK.
Now the image is small enough so you should be able to attach it to your next message on this thread.
