Download>Platform/Playlist/Category Theme Videos Error

[Mainiack]

When i go to Tools> Download>Platform/Playlist/Category Theme Videos I get an Error and LaunchBox is forced Closed.
I have reinstalled Version 12.3 over top of existing 12.3 but it didnt help. I clicked report error but when i got into bitbucket, I decided to come to the forum instead.

This is on Windows10 64bit if it matters.

This is the Error Message:

Do you have an EmuMovies password set in options? The tool doesn't require an EmuMovies account, just trying to narrow down a possible cause. Though this should be resolved in beta (once it's out). That form is being updated from the old WinForm code to WPF. Just trying to see if we can get this resolved for you until then.

I don't have an EmuMovies password set in options.

Can you just put random strings in Username and password in options and tell me if you still get that error?

[Mainiack]

No error after random entries for Username and password on EmuMovies.  I have reached the Downloads List. Thanks @C-Beats

Cool. Like I said this will be corrected in next version, but glad we found you a work around until then.
