[Plugin: Flashplayer] Code Instead of Player/Movie

Just upgraded my version of WP and thot it would clear the problem… but not so.

My flashplayer plays fine on the regular post pages, but when I click to display the same post in a category, only the code comes up instead of the player and my movie.

My current theme is Blue Grace. I switched to try it on PRINZ Branford Magazine and it does not show at all there on the regular post page (again, just the code comes up instead).

What is the trouble?
