PDF Preview Lost

Hi everyone,
I was exploring plugins, and I managed to do something to lose the embedded PDF preview; the item page shows only a thumbnail.

Do you have any suggestions on how to get back to the embedded PDF?
My PDF Embed is set to 500 hights and the ‘Object’ for the embed type (I belive that is a default, I tried changing parameters, but nothing happened).

Thanks,
Stasha
