[Plugin: NextGEN Gallery] Slideshow error after NGG 1.0.1 and WP 2.7 updates.

All browsers show this error

The Flash Player and a browser with Javascript support are needed..

I use this tag [slideshow id=1] ; if I set the W and H I can see a blank space the right size. but no slideshow.

I also have a custom field of

ngg_ir_Audio

but that does not play audio; it used to before the update.

any clues would be appreciated?
