"Failed to copy the file" error 5

Hi
A couple of days ago, this message appeared:
"Failed to copy the file
C:\[path to BeerSmith]\T-11471Tools.bsmx to
C:\[same path]\Tools.bsmx (error 5: no access)

The program is behaving as normal as far as I can tell, but the message keeps on popping up several times an hour.
When I hit "OK", I get another message. See attached pictures for both messages.

Any idea on what's wrong? I don't think I've done anything to cause this. The actual files in the BeerSmith folder are all read- and writeable.

I'm on Win7 64-bit, if that's useful for you.

Watch out.  I've lost data after such an error.  Check your data folder and compare the sizes of the .bsmx files to the older versions (indicated with a number, eg Recipes.bsmx Recipes1.bsmx)

Hi, and thank you for replying.

Actually, a simple restart of my pc did the trick...  :-[
I haven't lost any data as far as I know, but thanks for the heads up!
