Videos wont play in live photo gallery screensaver

I have been using windows live photo gallery as a video screensaver on my windows 7 64 bit system for a few months now.

For some strange reason it has stoped playing WMVs for no reason.
If I go into the screensaver settings and in the preview it displays the following error.

The screen saver can't start because there are only videos in your selection.

This has not been a problem before.

The videos play fine in windows media player and play in live photo gallery.
I have tried to reinstall the live photo gallery and this does not resolve the issue.
I also used to be able to change the display template of the screensaver but for some reason i cannot find this option anymore.

Please help.

Picked this up from a blog -
In my friends case, it didn’t though, she got the message “screen saver can’t start because there are only videos in your selection” . After some exploring around the fix for this turned out to be that the “Use This Theme” dropdown must not be set to Classic – but pretty much anything else works!

All i could see is this card cannot play themes.

It used to.

Tried an index refresh and that didnt fix it.

Ran a manual reg edit and that seems to have fixed the issue.
