How do you get this thing to unblock

[Pragmatic]

I accidentally blocked a program - no_tmrw.bat, with a name like that who
wouldnt, but now I cant manage my blocked items, the box just comes up empty

Make a copy of the file, and delete the old one

 

[Pragmatic]

I copied the file, I deleted the file, I renamed the copy, no affect still
blocked, any help?

 

[Mark L. Ferguson]

No, I don't see that behavior.
