Need help with spiralspy!

Well, I put spiralspy v1.1 in my spiral knights folder (where it's supposed to be) and it says: Error copying file or folder
Cannot copy file: Cannot read from the source file or disk
The original spiralspy worked perfectly fine and I had no problems with it, but my younger brother somehow found it and deleted it.
Why isn't it working and how should I fix this? Thanks.

That's unlikely to be a SpiralSpy problem. Something went wrong with the file you tried to copy, whether it was incomplete or whatever. Try downloading a new one.
I have this problem with any file when I copy from my USB drive and the drive suddenly loses power. Since the "source" got disconnected, that's why it can't read it.

i tried just about a million times today, same response.
bump.
