Pattern Fill not working

I am able to define a pattern

..when i go to fill a layer- I select the pattern, click the settings and hit ok- the loading bar pops up-then nothing, like it never happened. its still a blank layer.

Yes, I have the whole page selected. It's not working with script patterns eiter IE: brick.

Ive tried reinstalling and restarting. Also purging.

It worked fine last night, im not sure what the issue is. I did have to force close PS once, could that have messed it up?
