I have used the v 1.09.00 and it looks nice! But now I did somthing which caused the module to yell out an error!

I did som testing.  I did delete all files in the folder the module used and deleted the module from the page. Then I inserted the module on the page again and choosed the folder as before, but this this time the folder was empty. Then I got this error (below). So I did but the images (only original files, no thumbnails) back in the folder. The error is still there.

I tried to delet the module again and but it back in again but the error comes back.

What can possible be the cause?

Now I did open the filemanager and refreshed it. Then I went back to the page with the module and it works like charm!

First, I am happy that you got it figured out.  

It's kind of difficult to know what the original cause was without more details, but my initial guess is that DNN thought there was a file in your folder that wasn't really there.
