When I try downloading data for some movies, I recieve the following popup error:

An error occured: "Not Found".
Make sure your firewall is configured to let CATVids access the internet.

About 50% of the time, when this happens, it crashes the CATVids app.

As an example, it will always occur when downloading cover art for the movie Greenfingers from the USA site.

I am running:
CATVids v.8.23.02
Internet.dll v100
Windows 7

Any assistance will be much appreciated!

Please try the latest build (8.23.05):

Appears to have worked. Thanks!
