Snow 2.0 tutorial

i’m a newbie at flash, but i really can’t get the snow 2.0 tutorial to work. i’ve tried the snow 3.0 one without any problems - but I get this error message when I try the 2.0 one:

Error Symbol=snow, layer=Layer 1, frame=1:Line 1: Clip events are permitted only for movie clip instances
onClipEvent (load) {

Error Symbol=snow, layer=Layer 1, frame=1:Line 16: Clip events are permitted only for movie clip instances
onClipEvent (enterFrame) {

Total ActionScript Errors: 2 Reported Errors: 2

when i test the movie, flash also tells me it’s taking too long and if i continue my computer may become unresponsive?

anyone else have similar problems with this tutorial?
