Anyone see anything wrong?

Hi
Attached is the preloader frames of a fla file. I didn’t write it. The trouble is the filesometimes stops at 98% and freezes up.
Can anyone see anything in the code that would be causing this or is it being cause by slow computers and rather large file sizes? It is used in a series of swf files which are all about 1 meg.
I don’t understand exactly what the action script is doing but it looks like it should work.

Cheers
